Firstly, it is recommended that you pre-treat your flies like when using Loon Hydrostop. I didn't like dipping a dozen flies in the solution and leaving them out to dry overnight. I found it to be messy as the hackle still held a lot of the solution, even after blowing and shaking. In some cases the solution didn't dry completely overnight and it transferred over to my fingers the following morning.
Secondly, I found the Fly Agra darkened all my fly bodies making it very difficult to differentiate between shades and even colors. It completely took the brilliance away from the white bodies of my coffin flies making them look grayish and uninteresting to me, and probably the fish. It may work better with some types of dubbing than others but I have my favorites and they were the basis of the experiment. Hindsight tells me I should have done some test dipping first.
IMHO, this product is probably better suited for Trudes, Goofus Bugs and other western flies for fish that aren't as selective as ours. I wasn't at all happy with what it did to the flies I treated and am now re-tying all of them. This is just my experience and I'm passing it along for what it's worth. You might have a different experience. As for me, I'm back to paste-type dressings.
