What are you guys using to build up the body of a kaufmann stone fly? My flies are seriously lacking some bulk, and the ones that do have bulk, are closing the gap of the hook?

I've been using the TMC 200R hooks, with that nice curvature to them. Is this wrong?

Are you guys using lead wire and doubling/tripling up on the wraps to create a nice tapered weighted body?

Any tips on tying these suckers would be greatly appreciated!
