I'm going to be buying a new bowling ball eventually, and was curious about pin placement and top weight.

I'm basically just a stroker, however I'm wanting to become a cranker.

I throw pretty hard and even using old balls can get a pretty good curve.

I've talked to a few people who suggest I get a ball with a 2" pin placement and a 3oz top weight.

A few other friends I have said I should get a ball with a 2" pin placement and a 2.1/2oz top weight.

My question is... does it matter much for my style? And the difference between 3oz and 2.1/2oz, does that matter?

I'm kind of confused and I'm not even really sure if I'm posting this in the right forum?

Anyhow, help would be very appreciated.
