Hello, I've recently gotten into bowling about 2 months ago. I've been bowling fairly regularly during that time -- about once a week -- after rarely bowling in my life before that. My average is 130, with a high of 171. I'd like to get more serious, not only with lessons but with equipment. I don't want to use the house balls anymore, but as a beginner I also am not going to immediately invest in an entire ball arsenal right away. My question is: Is there are good "catch-all" nice performance ball I can buy to start with, so I can practice with a good ball, before I get into buying balls for specific oil patterns etc? Thanks for your help!
