Spoof,
The bucktail is tied in along with the hair at a longer length than the spun/stacked hair. Tied in like wings or even rubber legs, sort of figure 8 method. Hold out of the way when trimming. The bug is trimmed to sized working around the legs. As far as spinning hair on a hook, I use the flymaster plus as well. I have tried many others but stick to the flymaster plus. It's the one thread I can trust to take a beating and pack hair tight enough to be able to get a smooth body look after trimming.
