Schaller/Proline/Fender one I find the best. I've used them all & these never let me down once. Tighten the nut & peg holder to your strap using 2 adjustable wrenches or vise grips. Tighten them hard & they will never come loose. I've had the same set on my strap for 5 years now & I just buy new pegs for new basses when I get them.
