But my guess would be that Greg will use the NAH v2 ruleset as a guide and edit as he sees fit to create the EHBPC 2012 ruleset, the key (potential) additions would be things like steering/handlebar infractions, toppling, game delay penalties, who the ball is awarded to on game stops, ball-jointing/scooping rules, etc.
