I've had this ball for about 2 weeks now and all I can say is this Monster needs OIL!!!! If there isn't oil then the ball will burn up and use its energy quickly. I throw 17-20mph depending on lane conditions with 350-400 revs. I have to stand 10 boards left of center throw over 13 out to bout 8 and this ball comes back beautiful. If there is a lot of oil i just move right.
Positives: Needs OIL, biggest hooking ball I've had to date, when it hits it hits HARD.
Negatives: Burns up quickly if no oil, could of used a different drilling to make ball more versatile but ball still fits the bill for me.
