15lb versus 14lb is there that much difference in carry? Is there that much difference in the rev rate. If you went from 14lb to 15lb would you have your balls drilled to the same layout as to where the pin location is. I’ve been bowling about 3 months now.. I bowl a lot 5-7 days a week 4-5 nights I bowl league. Every other Saturday I’m bowling tournaments. I started with a average in the 130’s now I’m averaging 160 in league I’m normally bowling 30 pins above my average each night and my average is creeping on up. I throw 40-50 percent strikes and get a lot of 9 counts. Would going up in weight help that 9 count turn into a few more strikes? My high game a few Mondays ago is 275. I’m getting to where I throw more and more 600 series.. I’ve gotten to where I make a lot of my spares and getting a lot better at my 6 and 10 pin pick ups. Thanks for your help and time.
