^ yup, frogs fanny or any other powder dessicant works great. I used gink for several years when I was starting out because that was I all I knew about at the time and it worked ok but only after letting it dry for 5 or 10 minutes on a fresh, dry, unfished fly.
Once you use the fly for a little while and it dunks a few times in heavy water, or you catch a fish, the gink wears off and it sinks. Applying more gink on a saturated fly was a futile effort in my experience, and I believe I mentioned this difficulty for the first time to Bruce Fisher at pca on my first trip to Penns, and he handed a bottle of frogs fanny. I've been using it ever since. If your fly is soaked, just pinch it on your shirt (or a microfiber towel, which I do have now), and brush the desiccant on the fly vigorously, and it's good as new.
Imo, of your fishing cdc dries especially, you have to have this stuff. Also dh comparaduns, ehc, etc. Gink does work well for hackled dries in my experience though, but only on a fresh fly.
Another tip: buy two bottles of frogs fanny (or other powder) at first. When a bottle is full, a lot of the dessicant gets wasted when using it. Once a bottle is down to about 1/3 capacity, dump a little from the other full bottle into the near empty one a little at a time and keep your working bottle around 1/3 to 1/2 capacity. I've gotten much more use out of frogs fanny this way, and the stuff ain't cheap.
