well that was the problem hayesy people went in to the course expecting high tech drilling layouts and stuff when to be honest like u said it is a art its hard to make a 1 or 2 day course for drilling it takes experience and alot of trial and error. to be good at what u do and thats wat batson was explaining the course wasn't a failure its just that people weren't expecting what they got. that course was very beneficial if u got the cd he handed out and used it there is heaps of info rite at ur finger tips. when u drill eough bowling balls you will learn as long as u aren't righteous thinking you are rite all the time.
