Quoted from RussMyers:I really don't recommend leaving the bare metal post for the balls to bang into.
Cover the metal post with a segment of clear (or colored; they do some colors) plastic air hose used for fishtanks. It's thin and a tight fit over the post but prevents direct contact to the metal. Much smaller than the post rubbers. Also cheap as hell.

Well then.......here you go...found some translucent plastic tubing - durable and looks OK.....funny how much more noticeable the captive ball shot is now - let alone how much more effective it is in gameplay....
