Hi and welcome to the board.

Hmm, in no particular order, wet flies that I like include:
1) parmachene belle
2) royal coachman / coachman / leadwing coachman
3) invicta
4) bloody butcher
5) micky finn (streamer)
6) greenwell's glory
7) Pritt's Water Cricket (a softhackle, yellow floss body, black thread rib, starling hackle; size 14 seems to work best for me)
Baillie's Black Spider / Stewart's Black spider (another soft hackle, brown body waxed to black, starling hackle wound 1/2 way down the body).
9) white invicta (tie an invicta, but use white tail, grizzle hackle, white wool body, white quill wing, black fibres for the throat, sliver rib)
10) doc spratley (size 12)
11) waterhen bloa
12) bibio

I'll stop there. Dressings can be found online for all of those except the white invicta, as that's my own pattern, but basically just tie an invicta but use white material everywhere (grizzle for the hackle to give a bit of contrast, likewise the black throat).

I've also done well with squirrel tail winged streamers along with a number of bucktails.
