Hey Jemo i would divide that into wet and dry.
Wet: 1 - Sooty Olive (would not even think of going wet fly fishing without it) 2 - Golden olive bumble 3 - Red Arsed Peter (just slightly beats the claret dabbler).
Dry (really depends upon what is hatching at the time) But the Grey Duster is THE man! for general use. Great for olives and dry buzzers.
For dry sedges - small brown sedge with fox squirrel wing fly rite dubbing body and ginger hackle - truly unbeatable..............
For dry mayflies a CDC mayfly is brill.......................
