My wife and I bowled in a 9 pin no-tap sweeper on New Years Eve and had a blast. I bowled the highest series out of all the men there with a 717. I was on track to bowl a 300 in the second game, but I threw it through the head pin and left the big four on the first ball of the 10th frame. Still shot a 260 that game, though. Going in, I thought it would be easy to get a nine count on every shot, but it was a lot more difficult than I thought it would be. Like bill said, once you start shooting for nine, you'll only get seven or eight.
