Roto Grip UFO
Roto Grip UFO

Testing Information: 41-foot THS (medium to light volume)
Kegel Machine - Brunswick Anvilane
E.T. core wrapped in MicroTrax S-20 solid reactive coverstock equals a strong, rolling orb that plays well on medium to heavy volumes of oil. The UFO might not be the preferred choice (not that it couldn't play) on a house pattern but will be a good 1A ball in your tournament bag. I have the UFO with a touch less overall hook than the Halo solid. The MicroTrax S-20 cover gets the UFO through the fronts easily and the backend motion for us was strong, but controllable. Tournament season is upon us so I will get to spend a little more time with the UFO in the coming weeks.

The UFO is the new HP4 solid from roto grip. It offers the MicroTrax-S20 solid cover with the E.T core. The numbers on this ball are 2.52 RG .054 DIFF and a mass bias of .016. I have mine drilled at 60 X 3.5 X 25 which allows me to move inside and throw 13 to 7. Honestly I was pleasantly surprised in how much the UFO got of the spot. The MicroTrax allows the ball to get down the lane before making a big move towards the pocket. The UFO is comparable to the Gravity Evolve in that the are both high end solid asymmetrics, but the cover of the UFO gets further down lane with a massive backend where the gravity has SPEC cover and Cataylst core which makes it early and smooth. I cant say enough good things about the UFO. if you're looking for a big solid that doesn't hook too early but retains energy this is the ball. Get to your local pro shop and pick one up.

I would highly recommend
Use this ball as my go to benchmark ball for first game on fresh. Avg 240 on first games of the 3 game series over 18 weeks. Highly recommend for someone who is a tweener with moderate revs
