Complete rules for all AHPRA Bowling Ball Loft competitions.
BOWLING BALL DESIGN SUGGESTIONS
The launching will be from the away cell area. The flyer will be required to bring any and all in the way of towers, rails etc, that is not the norm at a launch. Do not expect to have a tower there to use unless you have made arrangements. In 2003 several flyers planned to use a single tower and it was damaged.
