The Motiv Trident Nemesis is being advertised as the strongest backend motion that Motiv has created to date. This is an area that Motiv has been working on for several years. Skid/flip motion bowling balls have been a weak spot for them and they continue to work diligently to bring that motion into their product lineup. With this new release Motiv has definitely made strides in that direction. Watch JR take the Nemesis to the lanes and you can see that this ball can corner, not just on great shots, but even on marginal shots.
