Re: Czech nymph hooks
Are they shaped like a scud, with a big hump back? I've seen the lead bodies that you can attach to hooks, but have never used either. You can create the same effect by using flat lead tape rather than wire. I finally found some in a fly shop but I've heard that golf pro shops stock it ... not sure why, I don't golf!
A swap I'm considering for the new year is a CZ style nymph, so you better get some of those hooks.
