I don't have much experience fly fishing, but I'd say 75% of my fish have come on a WB. My one adventure trip was on the N. Platte in Wyoming. We stopped for lunch at noon with a high sky. I heard a fish jump and stripped a black bugger through there and caught a 16" fish. It was like a fishing show, esp. since the 3 guys I was with weren't fisherman. Later that night I crept up behind some fish sipping something small, stripped my bugger through a hooked one. It was bigger than the lunch fish. I reached for my net, which was 200 yards away in the canoe. I lost it while I tried to wear him out. Long story, but it's my only one. I like them big, weight them w/ a couple shot, cast perpendicular or slightly upstream and strip them back. Usually get hit on the swing, but not always. I also like them in faster water.
