Hi. I just joined this community and wanted to introduce myself. I bowl in two leagues in San Diego and my average is hovering around 160 but it needs to go up! I practice constantly and have recently fixed some grip problems I had. I was using Rosin for non slip but in fact it was making me drop the ball more! I've moved on to grip cream and it's fantastic! I shot a 267 in practice the other night. By the way, I throw a Storm Vertigo.
