Only thing about putting the balls on the trap ring is that the chicken line is going to be pulling the ring INBOARD. So when/if you lose tug on the hook/ring, the chicken line could pull it out.
I was worried about that too and usually I have the chicken line under a little tension pulled aft and inboard. I figure my weight on the ring is enough to keep me locked in. I might switch it to my harness but I would rather not have 2 balls on the harness- yet more crap to get caught on stuff. I am going to switch the rings out for a loop of line with plastic tubing over it like robi has done and I will have to re-examine the set up.
