I've tried the sylk on bamboo and did not like it. it gets very sticky in warm weather. some say they don't have this problem, and others say they do. I did.
As for triangle taper on bamboo, I have not tried the standard TT, but I do fish a wulff long belly on an 8.5 5wt bamboo and it is wonderful.
gary - are you using that Wulff bass taper on a fiberglass? If so, I can imagine that it would probably be overkill. I think it would also make the tip give out on a soft-tipped rod like a winston or something. However, I recently put it on a loomis cross current 6wt and it is a dream to cast. The rod is sort of marginal with a standard WF, but the bass taper really makes it come alive.
