Alot depend where you are located. The adams is a popular fly. Better to go to a fly shop locally and get a few from the major hatches in your area. Nymphs, larvae, eggs, mayflies, emergers, duns, there are so many flies out there I have tons and tons. Prob way more than I will ever need. But I use alot of them. Some for lake some for river, some for trolling.

Here's a selection to get you started off:

Dry flies: *Adams, light cahill, dark cahill, *elk hair caddis, royal wulff, *AuSable wulff, stimulator, blue wing olive, blue dun, *march brown, gold ribbed hare's ear, light hendrickson, dark hendrickson, and Joe's hopper

Wet flies: *Partridge & orange, leadwing coachman, *hare's ear soft hackle

Nymphs: Pheasant tail, *gold ribbed hare's ear, stonefly

Streamers: *Wooly bugger, black nose dace, micky finn, *zonkers, *muddler minnow, hornberg, grey ghost, and black ghost

* = flies I use the most

Good luck!

It all depends where and when you are hunting. I like to use a brown drake in mid-summmer. A good overall choice is the wooly-buggy. If there is a local fly fishing shop near you, they could give you tips. BUt i really all depends on where and when. Sorry i couldn't be more helpful.

If I were you, I would just go to a local fly shop and ask them your question. Your fly selection is going to depend on where you fish and the local fly shops should know exactly what to set you up with. I do this all the time, especially when I fish new water.
