Dave is a long time ball driller and extremely accomplished player. We are honored to have him as a customer. In text book Dave fashion he bowled back to back 300 games to conclude a nice series of 837 with 31 strikes in a row! He did it with the Brunswick Danger Zone drilled by Bruce Irwin. Although Dave is getting older, he throws it just as good as his days on tour! --Thank you for letting us be a part of your success Dave!
