Scientific Anglers Magnitude Grand Slam Full Float Fly Line – Textured
Full Clear-Three-Quarter Heavy Line
Using naturally buoyant polymers, we’ve created the next generation of clear floating lines. With the option of a 10‘ clear floating tip that allows the angler to track the fly and a full clear floating line for the ultimate stealthy presentation.
Enhanced with EST+ slickness additive for unmatched durability, smoother shooting, and eco-friendly performance.
Shooting Texture reduces friction to deliver longer casts.
The perfect line for bonefish, tarpon, and permit on the flats; also great for snook, redfish, and sea trout.
Overweighted by .75 sizes to load rods quickly; short, powerful head turns over long leaders with heavy flies.

FAQ
What makes this fly line different from others on the market?
This line uses naturally buoyant polymers and features an EST+ slickness additive for improved durability and smoother shooting. The textured surface reduces friction, enabling longer casts and better performance in flatwater environments.
Is the 10′ tip useful for tracking the fly?
Yes, the 10′ clear floating tip allows anglers to track the fly more easily, which helps in maintaining better presentation and awareness of fly position in the water.
Can this line be used with heavy flies?
Yes, the line is overweighted by .75 sizes, which allows it to load rods quickly and deliver short, powerful head turns over long leaders when using heavy flies.



Nicola Fisher –
This line performs exceptionally well on the flats. The clear float helps me see the fly’s position, and the textured surface gives a noticeable improvement in cast length. Great for bonefish and permit fishing.
Caroline Reid –
I’ve used this line for snook and redfish and it holds up well in saltwater. The 10′ tip is very helpful for tracking, and the durability is impressive after several trips to the coast.
Irene Slater –
Solid performance on tarpon. The float is clear and the line feels smooth. A bit heavier than expected, but that works well with my rod setup for heavy flies.
Caroline McGrath –
The shooting texture reduces drag significantly. I’ve noticed longer casts and better control when casting over long leaders. Perfect for flatwater fishing with heavy flies.
