I never keep the 5 unders that I'm allowed at Shelbyville unless someone with me wants them. I have 20 culling rings and 10 small clips. If we decide to keep 10 overs and 5 unders, I put out 10 culling rings and 5 small clips. the culling rings go on each over that goes in the live well and the small clips go on the unders. when The cull rings and small clips are gone we know we have 10 overs and 5 unders in the livewell. We each have our own rings and clips to ensure we only catch our own limit. It's fool proof
