Its no secret that many fishermen when using a duo rig of some kind like to use the Elk Hair Caddis as the lead fly because of its flotation qualities. And it also makes a good indicator.
It just occurred to me, if a EHC is supposed to have a little skittering action, why use it as a lead fly? If you’re skittering that fly along with a trailing fly that’s supposed to have a dead drift, isn’t that defeating yourself? I can see it using two EHC’s, but even if you are trailing a nymph behind it, the nymph wouldn’t be acting the way it should.
Some say its just used as a natural indicator so not to worry about it because the focus is on the second fly. But if a fish takes it, no harm in that. Ok, that makes sense, but if the focus is on the second fly, just use the second fly by itself, or use two.
I don’t get it.
