As far as the dries go, they will be fished at some point (some of the wets, too). Can?t say I?ve had any muddler that doesn?t work; the inherent design is pretty bulletproof and even some of the more garish ones have proven to be very productive. It helps that I fish unpressured water and the fish are a bit naive; wherever I fish, I?ll change flies often just to see what else works.Regards,Scott
