WOW! used the TR2 during practice last night on the cheetah pattern,on synthetic lanes.First shot over the three board ,ball on the seven pin.Next shot with another TR2 shot over three board,ball on the four-seven.Picked up my SX1, ball over four board flush into the pocket.Both TR2's were 800 grit,which is what they come out of the box at,the SX1 cover was at 1200.I must say this is the biggest hooking ball by MOTIV and the earliest rolling.I still have to use these balls during practice and on a house shot this weekend before I can write a full review.But I can say this ball hooks as much as anything I have thrown.
