Thanx for the response and links. I will go with the explanations but at same time think the difference is one of culture and tradition. I do not believe (at this time) that using one versus the other will make for more or less fish caught. If I ever go to using Tenkara rigs I might find different but don't have the water for Tenkara use (I fish mostly lakes) and may never get the chance to experiment myself. I do like the looks of Tenkara flies tho and since I'm a consistent overdresser (differing from crossdresser) I think the McPhail fly is gorgeous.
