Bruce, If you're happy with the straps you use, why not consider "waxing" them with some saddle wax the "Horse Folks" use. Wax it, roll it up (both ways) and break it in, this shouldn't be a problem. If not, go to a nylon mesh type of strap. Good Luck, TJ Sullivan
PS Also, Check out your connectors, are you using Straplox or what? Maybe consider lubricating them.
