Probably not the answer your hoping for, but you might want to look into other options. If ya got the money, a Bib hanger would be a good idea. Also, Tom Hubbard’s AFB might be just what you are looking for. Check out his site and read some of the posts in this hanger forum for ideas. I never tried a swimcap, but as I recall alot of folks had trouble keeping the fucker on. Think of it this way, your spending the time with a weight on your dick so make it easy on yourself when it comes to the hardware. If you can get that swimcap to hold close to nine pounds, you sound like the type of fella who could whip out a quick AFB and fine tune it to suit your needs for under 5 bucks. groa
