My criteria are: At least 3 inches wide. Fully adjustable - without having to take it apart. Coarse enough not to slide around on my shoulder. I have a 3 inch wide web strap that meets two of the criteria but it tends to slide around. I also have a Levy's leather that meets two of the criteria but it's not adjustable on the fly. Sometimes my muscles need a break or I like to play w/ the bass higher if I've had some time off. I was checking out those Planet Waves straps on the web. Are they rubber or suede near the shoulder strap? Grippy enough??? Any other suggestions would be appreciated - The cheaper the better.
