Which rear suspension? 3 link? 4 link?

[CamaroJesse]

Ive been searching the forum for a while now trying to figure out what rear suspension is actually needed. On my 68 camaro i have dse leafs, bilsteins, and tubbed out back. It sucks. rides bad and wheel hops like crazy. So im looking into doing a link set up. But the question is which one to go with? I dont wanna spend as much as the LD 3 link cost although it would be nice.
Right now im looking into the detroit speed 4 link and the prodigy 4 link. They arent priced that high. I just dont know what to get. What are the differences? Its mainly a street car but will be road raced a few times a year and probably auto crossed alot. I just dont know what the actual difrences are between all these different set ups. Looking for something id be happy with and not break the bank.

thanks
