Hookedup,
I only run one copper per side. More that one will cause real problems. For releases, I use the Scotty Downrigger releases with a shower curtain hook attached. If you can find the Scotty double stacker releases, cut the line off and add the shower curtain hooks. It is around $9.00 per release if you buy them single. If you buy the double stackers, it will cost you about $2.00 more. They work awesome. Another trick I use is adding 6' of 50lb. mono between my backing and copper to attach the release to.
