they say there is no such thing as a stupid question,so here goes:back in the days of the pancake weight blocks and 1 oz. finger,thumb,positive and negative weights your driller had to use his do-do scale to keep the drillings within the legal weights.now with all of the differrent weight blocks and unlimited drillings a)are the do-do scales still in use and b)is it still possible to drill a ball "illegally" and c)do finger,thumb,positive and negative weights stillcome into play along with the max. 1 oz.?
