This is very nice foam and is easy to work with being that it is in uniform rectangular sheets. I use it for many stonefly and hopper patterns and am completely happy with it's performance, both at the vise and on the water. It floats for days and the fish seem to like as well. What more can you ask for?
I looked up some youtube videos and tied of some super effective extended body mayfly patterns with this stuff. Very easy to manipulate, and floats without any floatant for a long time. These were easier to tie than I anticipated and probably the most realistic flies I have tied to date. Great foam sheets and I love the color selection.
