I too, would rather have two corkies rather than one outsized one, for all the above reasons, but I always "pin" the top corkie, with a tooth-pick or twig so that they will stay together at all times and in place on the leader. When I tie my leaders, I always use 2 or 3 beads between the hook eye and the corkie/s, so that there is "bite" clearence. Same idea as runnin' a bead-chain under a diving plug. Get lot's more solid hook-ups for sure!
