Not very often. I used to make fancy extended bodies for things like big early march browns and Isonychias on Penns where they can be huge, but I quit. For those big flies, I find I can get overall better performance casting, riding, hooking, durability, time, all that, by sticking to standard ties on just 12 and 10, 2XL hooks. I use those almost exclusively on Penns. On other waters, a shank size 10 or 12 will work for those bugs. Except for the big brown & green drakes, there are no bugs I tie dries for that exceed that size.
For golden stones, I use a sz. 8 tiemco 200R for the nymph. I don't fish those all that often. I gave some to a former student and he knocked-em dead on Brokenstraw and uses them a lot up there.
