I don't think I could name a favorite-
I like fishing flesh flies because I can watch these very visible flies on the drift- I love seeing the flash of a big bow come out of its hole and nail one!
I also like sight fishing for bows and browns with small egg patterns like beads and globugs- Watch for the white of their mouths open and set the hook. Very fun, frustrating, but I'm a perfectionist and this kind of fishing appeals to me.
Some of the funnest fishing I've ever had was fishing for grayling up in AK with drys. I found nearly every pattern in my box caught fish, but obviously the more buoyant and water resistant, the better.
I'd say my favorite 'drys' would have to be large foam terrestrials, and hoppers- I like catching big fish and these are usually my go to at the right time of year.
