The pearl Sigma Sting™ is tuned for medium oil, making it an incredible benchmark ball. It provides great length and a smooth, but angular backend motion that continues confidently through the pin deck. This is the first time MOTIV has put a pearl cover stock around the Sigma™ core.
The Sigma™ Sting from MOTIV™ is an incredibly versatile benchmark weapon that will be used by a wide array of bowlers. It is a must-have piece for bowlers building a solid tournament arsenal. It also provides the perfect shape for many league bowlers that need something angular, but not too jumpy on a house shot.
