friend of mine with a rule drilled by none other than tenpinspro shot 300 last night in my travel league.  oil was wide and long on his pair.  i watched the last 3, straight up 5 with a savage turn at about 45' into the pocket.  pretty awesome sight watching a good bowler with an excellent ball.  had to kid him however, shooting a 6 without a deuce.  in fairness, the backends were a little tricky and it took him a while to figure out the angle to play.

second sanctioned.  the first one was with the used ball that you redrilled for him.  i think he said that there was one also in the eighties that was disallowed due to the lane verification procedures in place at that time.
