After reading the strap positioning poll, I got to wondering about straps, again. I've been using this Yamaha 3" leather strap for almost a year and a half with my Ibanez SR506 (fairly hefty bass), and it's not a padded strap. I believe it is adding to my shoulder cramping and stress, and I'm starting to look for a better strap. I like wide, but I want it as comfy as possible. I want my bass to feel lighter, and balance better. This is why I've been thinking about a Slider Dual-Shoulder Strap (I believe that's the name). Any experience with this device? I was just thinking that having the weight distributed over both shoulders would greatly reduce stress. Can I get some help? I'm 17, been bassing for 2 and a half years, and it's already killing me physically. What should I do!?!?
