i'm using the stock fender bridge on my aerodyne with graphtech saddles... i asked cherns to help me bring in a hipshot vintage bridge, because it's the only thing that will fit into the bridge cavity of my bass
main thing you wanna look out for is the design. the idea is for the bridge to transfer energy from the strings into the body. if the bridge is flimsy or poorly designed, alot of energy will be lost at the bridge itself, and that will affect your tone and sustain. mass matters less than good design, though it does add weight to the bass body to prevent neck dive.
the best way is also the most expensive way, which is to experiment lah bro
