The internal construction of the Roto Grip SD73 creates dynamic energy, which combined with the Sure Grip coverstock, provides acceleration through the mid-lane and a backend reaction with unequaled power and control. The Pearl is cleaner through the fronts maintaining more energy for a stronger move on the backend.
The all new SD73 Pearl will do for the sport of bowling what the AC Cobra has done for racing. By giving you the "unfair" advantage, the SD73 Pearl will keep you at the top of your game.
The new SD73 Pearl features a coverstock that is so aggressive, it is not allowed on the PBA Tour. Combining this coverstock with a low RG weight block that pushes the ABC/WIBC limits of differential, this intense ball is sure to outperform the competition. Although this ball is near ABC/WIBC limitations, rest assured the SD73 Pearl is approved for ABC/WIBC competition and is legal for all ABC/WIBC sanctioned competition.
