I've tried 'em all. Comfort Strapp, that stinkin' Slider strap, everything still hurt my shoulder after about 45 minutes. My mail man came into the office where I work, and I immediately noticed he had a new strap on his mail bag. I asked him about it and he told me that he got it from a postal supply house. http://wassermanuniform.com/noashok.htm It's called the Shokstrap. About 3 3/4 wide, heavily built, padded, and thick elastic straps on either end of the pad. Of course, I had to make some modifications to it since it was made to hold a mail bag. It was SOOO worth the effort!! I know I'm not the only one here with shoulder and back problems, so I thought I would pass this along. Oh, by the way, if I remember correctly, it cost me only about $30. Best $30 I've ever spent on bass gear!!
