RotoGrip UFO Review by Casey Murphy
« Reply #31 on: May 22, 2020, 09:12:57 AM »
Orientation:  Right Handed
Rev Rate:  400 RPM
Speed:  16-17 MPH
PAP:  4 5/8 straight across

Location:  Enterprise Park Lanes, Springfield MO
Pattern:  High Volume THS
VLS Layout:  5 Ĺ, 4, 2 ĺ

The UFO is a great benchmark Asym from RotoGrip.  Iím a little on the slower side of ball speed and I tend to roll it a little heavy.  As a result, I canít throw SUPER strong balls usually.  But the UFO is just clean enough that Iím able to use it more effectively.  It hooks a ton overall, itís definitely that strong solid asym shape but just clean enough for rev dominant players.
