I'm intrigued by the balanced leech concept. I have had great success with a more standard "micro leech" pattern with a tungsten bead at the head on certain days, but other days it won't get a sniff. It's a fun way to fish (in my opinion).

I wonder how much a balanced configuration would improve my rate of success. For that matter, I wonder if using a lighter bead (brass) and placing a half hitch in the tippet, on the body behind the bead, of a fly tied on a standard hook might achieve a similar, "balanced" effect. I may try this first, as while I think the balanced leech is a great concept, I see it taking me quite a bit longer to tie one of those than it takes me to tie a standard micro leech, and I'm usually in a hurry when tying trout bugs.
