Screwball, I said that the slingshot is slower than windmill, not by a whole lot, but certainly noticeable. I have played against slingshotters and used to see a fair number of them. I know several men that were playing "Open" modified fastpitch a few years back and their speed doing slingshot was slower than their windmill but still very fast. I also know from personal experience that I can throw harder windmill than slingshot. It makes sense that you can anyway.
