I watched a 104 on 196 average last night and the guy was really trying, he looked like his eyes were going to pop out of his head.
I had a 158 a few weeks back and still managed a 608 series, only took 2 ball changes to find the right ball after changing hand and speed for the 158 game

I also shot 88 once in league my first year, lowest game by a man the whole season and should have been. It was nice and humiliating for me, but made me seek out coaching and the dreaded new ball kick I got on.
For 2 years believe it or not I had only 1 bowling ball, seems like a million years ago now it 1998 and 1999.
