What I think it boils down to is evolution of technique. When the first sink tips came out the old timers would say things like "The trick is getting the fish to the fly not the fly to the fish" and were ticked by the sink tip guys. Now it is the sinktip guys calling Pooh-Pooh on the indicator/Nymph guys. I am like Sparkey I fish how I think I have the best chance of catching a fish, that fits inside the regulations. Or however I am having the most fun (chuck and duck makes the back of my head and my ears hurt after a while).
