Ideal for longer back casts

Lock Proline Max Overhang Marker Floating Fly Line

Sale price$115.45 USD

Ideal for long stable casts where you have more back casting space

This is the all-round line you can fish with lures, streamers, dries, and nymphs without changing anything. The stable head carries and holds shape in the air, so it doesn’t collapse when you carry more line. Leaders turn over straight and tidy, and the Overhang Marker makes every cast feel predictable and repeatable.

Plugs into the Lock reel or wind it onto your own reel's spool.

Underrated line

I ordered this line March 2025 and there was a delay in production so I had to wait a bit longer to receive the line. Sunray's customer was super helpful and easy to communicate with (thank you again Hayley). 2 months or so later I received my line with a ton of extras I didn't expect.

The line is great, I use it on a 9wt rod for saltwater fly fishing and freshwater largemouth bass fishing. I fish 4-5 times a week off the shore and on a boat and this line was easy to cast and shot far. I don't know what the temperature range for the line is but I've used it in sub tropical and near freezing water temps without issue. I would buy it again when the time comes.

what a lovely casting line

i originally bought a 5 weight line at the start of the year, yes it was expensive for me at £60+ but split via Klarna it was possible... i love this line. recently a offer came up for a 3 weight line reduced to £40+ which again i used Klarna. if you are reading this asking if the line is worth it...you bet it is you will not be dissapointed

Improved my casting!

I took up fly fishing three years ago at age 75–so I don’t have decades to learn. This line has helped me make longer, more accurate casts w less effort. The overhang marker has flatted the learning curve on my double haul. Will only buy Sunray lines from now on.

That's good to hear Paul. Hopefully you're picking up tips from our Masterclass tutorials on the website too. Thanks from all at Sunray HQ.

New Sunray Proline Max 1 weight medium-head Fly Line Review

The things that first impressed me about this line whilst loading it onto a reel were how slick the surface was & how free of any memory it was. The hardness of the surface did not appear to adversely affect the line’s suppleness & despite Tom’s advice that it needed a gentle stretch before use I found that this was not necessary.
So how did it perform in real life fishing? My first tests were casting on a local small still water using a range of rods from a soft/full action 7’ 6” 1 weight Orvis Superfine to my favourite general purpose river rod, the Sunray Microlite GT 10’ 4 weight. Casting was flawless with all the rods at both short & long range, even the 4 weight. Whilst for most of my river fishing I would very rarely have more than the head outside of the rod tip, the presence of the obvious purple overhang marker ensures that the correct length of line is outside the rod tip when casting longer distances. On my return home I called in to my local chalk stream where I saw a couple of trout on the feed. Despite a brisk easterly wind & the 1 weight line teamed up with the 10’ 4 weight Microlite GT I had no problems casting a size 20 nymph the 40’ to the fish on the far side of the river: result a lovely wild brown trout.
Now I must confess to being less than keen on welded loops & this line has one at each end which makes the attachment of backing & leader simple. I normally use either a knotless, Super Glue join, Needle Knot or Nail Knot join with a leader of between 12’ & 15’, plus 3 to 6’ of tippet: these ensure that the join easily slips through the tip ring, avoiding damage to the rod or the loss of a fish due to the join jamming. However, the small, slim, well designed, loop at the tip of this line caused minimal resistance to slipping through the tip ring when I had attached my 12’ 6x leader with a 5 turn half-blood knot, sealed & smoothed with a drop of flexible UV resin.
Since my first trials with the line I have regularly used it to fish small streams with my 6’ 9” 3 weight bamboo rod, teamed up with a leader of 12’ to 20’ & on my local chalk stream, Driffield Beck, on some windy days, with my 10’ 4 weight Microlite GT rod, teamed up with a leader of 16’ to 20’. So far I have used it on a total of 25 days’ fishing. It performs impeccably at both short & relatively long range, roll casts effortlessly & floats well.
I love the delicate presentation of the Sunray Jeremy Lucas 1 weight line & when fishing small overgrown streams the quick loading of the Stuart Crofts line, but The Proline Max is, in my opinion, an ideal ‘All Purpose line’.
To say that I am very impressed with this line is an understatement.

Now that's a review David! Very informative and helpful for other customers deciding which line to select. Thank you, from Team Sunray!

Despite a very brisk easterly wind it performed impeccably

I've been very impressed with the performance of the new 1 weight Proline Max. Yesterday, despite a very brisk easterly wind it performed impeccably even though I was using my 4 weight 10' Microlite GT rod on an open Mulberry Whin fishery. Very slick, hard surface but still very flexible & no memory so I didn't need to stretch it & it floated well. I'm not too keen on loops at the tip of lines but the loops were small & slim so they passed through the tip ring with little difficulty.

I’m a beginner at flyfishing and my casting needs a lot of work. Bought this on a whim and spooled it up just to see. I’d been using some cheap stuff that came pre-loaded on a starter combo. But the difference this line made to my casting was nothing short of miraculous. Just a simple pickup and laydown cast will shoot an extra twenty-five feet in my not-at-all capable hands. False casting? Don’t expect to do so more than once, and make sure you have a heck of a lot of room, because this stuff just flies off the reel. Incredible.

Floating Fly Line

I started researching fly lines after coming home from spending the summer at my place on a remote river in Alaska. I had bought some cheaper brands the previous years and they were all terrible. I read about SUNRAY lines and waited for them to go on sale and bought the PROLINE MAX. When it arrived I spooled it up and did some casting in the yard. Needless to say I was quite impressed. I tried a couple of high quality lines from US companies and neither of them approached the Proline Max for distance. So now I have 12 new SUNRAY fly lines in my dresser that are going up to Alaska with me this summer so I can re spool all my reels. Great price for the lines too

Made me a better caster

I ordered the Proline Max Floating Fly Line 4 wt with Overhang marker. I only lawn cast it but could not believe how easy it was to cast to more than 40-50 feet if needed. It formed tight loops and very accurate. Can’t wait to try it on the water when temps warm up some more.

Great customer service

Hayley really helped fulfill my order after receiving a rod daged in shipping. They send a new one and even expedited the delivery without any extra cost.

Best budget floating line ever

This is my second proline Max floating line. I found them to be great casting and Will throw out large as well as small flies they may be do not last as long as premium lines but I am sticking with them
Just one other thing, I find them slightly heavier, so I order one size smaller and that does the check perfectly

These lines are brilliant I now have a few of these sunray lines I won’t use anything else now

Thanks, Paul! Really appreciate your support — so pleased you’re loving the Proline Max and sticking with Sunray lines.

Proline Max Floating Max Cast

Performs great in both floating and casting for dry fly and nymphing. The overhang indicator is very useful in maximizing casting distance. I have used both 5 and 6 weight lines and love them. I just ordered an 8 weight for my bigger fish outings!

Thanks for the great feedback! Really pleased you’re enjoying the lines and finding the overhang marker helpful.

It's not just our coatings that are bullet proof

Reinforced welded loop

Our welded loops were already the strongest on the market. That wasn't enough for us, we went one step further and wrapped our welds in a micro thin film of protective tubing. Supple, strong and slim.

The Overhang Marker took the guesswork out of my casting. I get it just out of the rod tip and let go. Works every time.

I needed the fly line for a competition. I ordered on Friday and it was on my door matt Saturday morning, amazing.
I had confidence in the fact the core was made by Dupont and the coating 3M. I wasn't dissapointed. Wow!
I couldn't believe how quick it was delieverd. It felt like I had just placed the order and it was there! All the way from the UK in a matter of days.
Despite Brexit I took a chance ordering from this UK company. Yes, I had to pay taxes but it's the best fly line I have ever bought and it was cheaper than the American brands.
