This stuff is a must have if you'll be throwing dries all day. I go up to the Snake in Idaho for the Salmonfly hatch and I would hate life if it wasn't for this silly powder. Make sure to blow the excess water off your fly before you dunk it in and you're right back floating high.

This stuff works well - it'll float your fly for a reasonable time and after you dry the fly off a bit, it'll have it floating again. But it dries very very white. Most of these liquid floatants dry white to some extent, but this stuff turns your fly white. If you're using a light colored fly, then it's not a big deal. But if you're using a dark fly... now it's mostly white.
