Re: Two or more flies?
Sorry I got in on this after the votes were counted. I fish two fly systems a great deal of the time, generally either on new water, or if I'm not sure where the fish are going to be in the water column. I'll also often drop a small emerger or soft hackle off the back of a bass popper so the bluegill keep me entertained until ol' bucketmouth comes along I sometimes think the distress of the small bluegills being caught gets the basses' attention and brings them up to the popper.
If it swims and eats, it'll eat a fly.
