I was wondering if anyone could give me some advice. All opinions are welcome. I'm fairly new to bowling so I don't know to much about all the specs on telling someone your bowling styles. I guess I would be called a stroker. My ball speed is around 13 to 14 mph. I stand a little bit left of the middle of the lane and throw it towards the gutter and it breaks back. I guess it could be called down and in. Sorry. I hope to learn all the terminology soon. I own a Supernova right now, but I bought an X-factor because it had only 15 games on it and I wanted to try a pearl. It was also pretty cheap. I want the ball to have more length and break later. What drilling layout should I use? Thanks.
