Scientific Anglers Mastery GPX Reviews

A Great Buy at Current Price Review by John E
Posted on 11/17/15
Scientific Angler Mastery GPX is a great all purpose fly line. Every once and a while manufacturers feel the need to invent a new model, supposedly better than the last. We then must have the "best and newest". This line is as good as it ever was. The WF 3 and 4 would be hard to beat for my needs and can be picked up at bargain basement prices.
GPX Can't Fail Review by David

If you have a fast action rod, this is the line for you. I use this line on both my 3 and 6 weights and it's perfect. The extra line weight really loads your rod and lets you throw beautiful, tight loops. I fish this both on trout streams and lakes and the line has no problem in Minnesota's warmer lakes. It will also handle a wide variety of flies: nymphs, dries and big bass flies with ease. There are few guarantees in fly fishing but the GPX is one.
A perfect Review by Salem

This fly line is perfectly associated with my fishing rod "Hardy Zenith". The line is exceptional and is fully adapted to actual fishing rods with fast action. Recent rods require more a fly line with 0.5 weight more than the line of the rod. My rod loads well with it : at short, middle or long distance, the accuracy is perfect. The line floats very well. I bought this line in Chartreuse color and it's very flashy.

First time using this line and wow, it is great. Loads great on my Hardy Zenith and casts so easily.
Best All Around Fly Line Review by adam

This line casts beautifully and loads my rod as it should. I usually tie my leader to my fly line so the built-in leader loop is not a great addition for me. However, I could see it being convenient for others. The line is extremely easy to manage and shoots easily. I have noticed the tip of the line sinking relatively quickly even though it is supposed to float better than the old GPX line, but no line floats great all the time. In all other regards, this is a wonderful fly line in my opinion. Remember this line is ½ weight heavier than a typical line of this size which works better on my fast action rods.
