Who makes long(er) straps?

Who makes long leather straps? I know this is kinda out there, but guys like Levy have straps that are just too short for me. I'm a brickhouse kinda guy (no, not in the Commodores sense), so they make the bass ride to high for me. The nylon slider straps usually provide me with about the right length, but are a tad on the thin side for my shoulder (putting in long hours of band practice). Any suggestions, or is this just one of those things nobody knows?
