Pennsylvania mens State tourny is like that. Two balls on each lane. What kinda crap is that. You pay the entry fee and you can't even get enough throws to practice, let alone warm up. I need at least 10 throws just to get my thumb comfortable in the ball. Somewhere after my fifth ball is when I start to look at lines.
Anyways, find a local who bowls the house and ask how they play there. that helped me last year. The local said they play outside, down and in, it's not my prefered shot but I threw the line my second game after trying to play my normal line. Ended up with almost 700.

As with all things, this is my opinion. And we all know, opinions are like butt-holes, we all have one.
