I make my own leaders and came up with this question. I was fishing with a thread 6/0 uni-thread leader for dry flies, and the leader sank. I put on some mucilin, but it still sank. So, is the wax on the thread making the fly sink? I was thinking of using the gudebrod rod wrapping thread (no waxes) and soaking them in the loon silicon stuff, or in watershed and letting them dry. has anyone tried this? How do ya'll make your furled leaders float?
