Overview
Roto Grip rebuilt its E.T. design as the Clone, tuning the core density for lower RG and higher differential. An OptiTrax cover balances oil displacement and absorption so skid, mid-lane traction and backend response stay consistent.
Predictable strength is why to choose it: high hook potential with a cover tuned for even response down the lane. It arrives with no holes, so a drilling appointment is part of the purchase.
Who it's for
Bowlers facing medium to medium-heavy patterns who need hook without an erratic backend will get the most use. Beginners and players on dry lanes should look at something milder.
Pros and cons
- High hook potential
- Published RG and differential
- Cover tuned for consistent response
- Shined finish adds length
- Too strong for dry lanes
- Package weight much larger than one ball
Performance notes
A low RG core rolls early and a higher differential produces more flare, which adds hook potential. The shined Reacta Gloss surface delays friction for middle length. The cover chemistry aims to absorb and displace oil evenly, which steadies reaction shot to shot.
