I love that mold. I just shoot and hold pressure for a few seconds and then fill the spur. It's a pretty easy mold. I'm thinking on buying three more molds so I can shoot four at a time. It is taking me for ever to make a dozen baits one at a time. I think once you get the hang of it you'll like it. I use it on a shaky head or as a jig trailer. I caught a lot of fish on that bait last year. It's a good one.
