I like the tube bodiz OK for larger patterns, but the BWO version they offer is way too big for most baetis flavors that I have seen. I tried cutting it short, but it was still a bit thick. i think FEB is a good option for even tiny fall BWO. I use a mix of olive, dun and brown EP fibers. The trick is to use a very small bunch, so you wind up with a very slender body. Tied to a small scud hook with a poly post and a few turns of hackle makes a very convincing BWO parachute. I also like it with a small clump of snowshoe for a wing. They can be tied very small and slender, and float well. A standard light wire scud hook is good and the Tiemco 212 is similar shape with amazingly light wire
