Rated 5 out of 5 by Great all around fly-line Picked up a spool of this for my new 4 weight rig. Very pleased. I can get some really good distance. The line floats very well, doesnt freeze up like my textured line. December 10, 2011
Rated 5 out of 5 by Best Fly Line I've Ever Used! I have not been fly fishing very long, and before this line I was not the best caster to say the least. As soon as I started casting, I immediately noticed that my loops were far better then before. In fact they were so much better that I was able to false cast over 40 feet of line and shoot much further. I primarily fly fish lakes here in San Diego, so I need to be able to shoot a long distance from shore. Matched with a Sage Flight rod and a Lamson Litespeed reel, I feel confident that I can accurately cast to anything from bluegill to carp with little effort. Overall a great fly line for any presentation from dry flies, all the way to nymph's and streamers. June 26, 2010
Rated 5 out of 5 by Best Line I've Used!!! This is by far the best line I've used so far. I'm still somewhat of a mediocre fly angler, but this feeds beautifully out of my G. Loomis Eastfork reel. I've never had a problem with this line hanging up in the eyelets. It feeds so smooth and my casts are much more beautiful. Great buy for anyone who needs that extra help! November 12, 2008
