I have a XXXL and I have been playing the dry track area on wood lanes. This ball is great, carries everything,trips 4 pins rips racks, evens sends messengers. I tell people I paid $10,000.(you get what you pay for). Actually, you can buy this ball (nib) for $120. I throw in ball between 15-17mph, and have med revs. Don't be afraid to buy this ball.
