I have not been a brunswick fan for many years and have not tried them since the Danger Zone.I am sixty-three years old and have been bowling in this one house for about seven years and have never averaged over one ninty five. I must admit that it is not a high scoring house and we have lost quite a few bowlers because of this.My ball driller told me that the AI would be just the right thing for me in this house so i said lets try it because i have nothing else that works there.He drilled it 4 1/2 by 3 for me.Now this was three weeks ago and i have shot 686,724 and 704.I understand it is to early to state this is the best ball out there for us seniors but if i keep bowling like this maybe i will just keep my mouth shut so nobody else gets one.All i can say now is thanks Brunswick.
