Very simple solution, assuming you're using hard weights or threaded weight pouches: Rubber belt and standard stainless steel pinch buckle. Never shifts around.
I used that combo in the Quarry for a few dives. Worked well. Everything stayed in place. The one problem I had though was that the rubber belt was quite soft/flexible, which made it a bit of a struggle to don the belt over the crotch strap (wearing full gear essentially). I can see it being a good solution if you're using a regular BCD and can put the belt on first.
