I'm in the market for Hatches II. I found it on Amazon--it seems to be about everyone's bug bible. Ted Fauceglia's book is also another one I have marked for future purchase.
Bamboozle, I tie my olives gray, too. I've actually never really seen too many olives that were an olive color around Central, PA.
As for emergers I've been tying them dark brown with a gray CDC wing. Sometimes I fish them in the surface or as a dropper with a larger nymph as the point fly. I think I tie them in 18 & 20.
I really enjoy exchanging information like this--you learn so much no matter how long you've been involved in the sport.
And, I carry way too many flies around with me. I guess I'm a bit OCD. LOL!
Thanks
