In today’s bowling world, there is an increasing demand for many players to reduce ball motion rather than enhance it. As bowlers have become more proficient with more fluid physical games leading to more efficient energy transfer, ball speeds and rev rates have increased. Higher rev rates lead to ball motions that transition too quickly, leading to over/under reactions on the lanes. Many bowlers want an alternative.
Accordingly, more and more bowlers are now looking for smoother and more reliable ball motions to add to their arsenals. For example, bowlers have sought out layout solutions such as the Rico (45° x longer pin to PAP distance x high VAL angle) and the Boomer (long pin to PAP distance and very large VAL angle with the pin under the thumb). These are intended to produce smoother and more reliable ball motions. In addition, we have also seen some changes in the bowling balls themselves with the evolution and popularity of weaker equipment, such as the Storm IQ Tour series (RG of 2.49″ and 0.029″ differential) and the Hammer Arson Low Flare (RG of 2.48″ and 0.020″ differential).
Consistent with this trend, I present another option for bowlers seeking a smoother back ...
