Here I go again. Every time I get used to something a supposedly improved procedure comes along. I have been fishing tandems/droppers for a while now with the dropper[trailing?] fly tied to the bend of the fly tied to the leader, then I go and read that the preffered way is to the eye of the original fly. I put the article down and tried to envision the differance. Is it possible that a dropper tied to the bend could impair the first flies effectiveness?
