some thing else forced upon us ,whats next ,its a trial thing acording to the rpra ,then why not just get a club to try them ,only any good to the ets users the rings will add seconds to some one like me ,because i put a address ring on one leg ,and have my race rubber put over the ring on the other leg ,so if i use these rings i will have trouble geting the rubber of over the stupid lugs ,plus cause the bird some more stress by me strugling ,,i wonder if the threat of court action because they are being unfair to us clock users will have any affect ,like the threat from the disabled did to get ets in ,im not against ets ,just the RPRA .lol.
