I just bought myself my first ball stretcher and im pretty excited. I know once i have it on i will be constantly aroused. I have done a lot of reading on the subject but have never actually had weights. I bought an 11oz. Clamp style with 2 hex nuts to close it. I figured 11oz would be a better start than 8oz because i would get bettet long term use out of it. I can barely wait for it to get here!!!!
