Hes definitely highly knowledgeable about all the equipment he sells (including thinking outside the box regarding which of todays various ball layouts drilling layouts options to pick out best suits the bowlers style and skill level.Quick about ordering whatever ball you decide on, and usually will ship out and arrive at the shop the very next day! Mike doesnt hesitate to then get the ball up onto the drill press to begin punching a few holes in it.Finally, the most important piece of information.....
