if you've git a Hipshot bridge, then Hipshot Ultralights would be the matching choice. Compact and you can get versions with clover, mini clover, lollipop, Y or short shaft Y keys if you want them. Never cheap, but they are great quality and can be moved over to another bass. The keys are reversible so you can swap from a 2+2 to 4-a-side (or even 3+1), configuration. And being light, they'll help balance the bass.
