"wet fly"? What kind of wet fly? A soft hackle? Chironomid? Damselfly nymph? Streamer? Woollybugger? Yarn egg? Blob? Sorry, I'm not intending to sound like a sarcastic curmudgeon (but I guess my response sort of does). I use a large variety of hooks depending on what wet fly I'm tying. I have a couple favorites for chironomids - Daiichi "Alec Jackson covert nymph hooks" being (for the time being) my favorite. Then again, sometimes I want a different profile and have tied hundreds of midges on TMC2457's. For more generic wet flies, and since I got a screaming deal on 100 packs, Daiichi 1560's for many wets (especially something like a snail pattern or waterboatman). But then my friend Rex started tying boatmen-ish patterns on something like a Firehole 315 (big).
I LOVE jig hooks for jigs (aren't they a wet fly?) and my hook manufacturer selection is all over the board.
Fly tying hooks are sort of like boats; one style (or one boat) is never enough. Good luck!//Patrick
