Sean I hate to admit it but I broke down and paid $5.00 for one of those things. It just looked SOOO yummy and the shop did not sell the plastic stuff to make my own. I'd have bought a dozen if they charged what they're worth in terms of material and effort.
Of course it's not for the purists among us. Just one step up from a sluggo on a fly hook. Which reminds me......where did I stash those 3 inch sluggos?
