Re: What are your favorite brook trout flies?
Brookies are not pciky. Throw an apropriately portioned dry fly (brookies are not adverse to flies seemingly too large for them) or a flashy nymph and they will probably go crazy for it unless they are under a lot of pressure.
I have had most success with #12 Yellow PMX dry flies as well as #12-#16 yellow and orange stimulators.
Brookies also like the color chartreuse a LOT.
