The brand new Roto Grip Duo is the results of a collaboration with PWBA stars Stefanie Johnson, Shannon O’Keefe, and the Huge Brothers Huge Sisters group. It pairs the polished MicroTrax Pearl coverstock used on the Unique Gem with the brand new Mentor core. This symmetrical weight block design provides the Duo a 2.49″ RG and a 0.046″ differential. It is a barely increased RG and decrease differential than each the Torpex core from the TNT and the asymmetrical Defiant core from the Gem line. The Duo supplied quite a lot of versatility for our three testers, and its versatility was additional enhanced by how effectively the coverstock responded to floor adjustments.

Tweener edged out the opposite two testers together with his response throughout all 4 check patterns, and he began putting shortly with the Duo on the contemporary medium oil sample. From the identical line the place the Duo was putting, he noticed the Unique Gem leaving 4 pins, whereas the Hyped Hybrid would depart 2 pin combos. The Duo allowed him to simply keep forward of the sample when it began to interrupt down by making small 2-and-1 strikes inside. If he needed to remain straighter up the lane towards the monitor space, he might improve his ball pace and roll up the again of the ball extra to maintain it within the pocket. Tweener discovered a really good line to the pocket on the dry check sample as effectively. The shiny end on the pearl coverstock gave him the size he wanted, and the again finish movement was sharp however controllable. The MicroTrax Pearl
