I'm bored so I thought I'd post a late night review of this ball. I bought it about a year ago as a heavy oil ball when I first returned to bowling after about an eight year layoff.
Anyway, the ball is drill with the pin even with my ring finger 3 3/8" from my pap with the MB in the strong position about 1" to the right of my thumb. The surface has been taken down to 800 grit per the Ebonite surface chart. So, it's layout out for the earliest roll and max flare. Like most bowlers who buy a particle ball, I expected a huge back end reaction. So, when I didn't get one, I was extremely PO'd. Also, using it on a drier lane conditions and watching it hit like a wet noodle didn't help matters either.
Pulled this puppy out of the box in the back of the closet to use in a league that has heavy oil in the middle with dry from 10 to the gutter using Guardian heads with wood mids and backends. Anything thrown deep into to the dry over reacts and the ball dives through the nose. If you use anything other than a ball meant for oil while playing the oil, weak 10's rule the day if and when you got to the pocket.
Standing on 25, throwing to 15 at the arrows and a breakpoint at 10, this ball would cut through the oil and make a nice smooth move into the pocket with great carry. 10's were no problem and were sucked off the deck with this ball. As long as you could keep this ball working in the oil, it did a great job. So, I made adjustments during the three games going deeper into the middle of the lane as the oil moved and shot a nice 650 series with it.
I would highly recommend this ball as long as you have the oil to make it work. I can guarantee that if you use it on anything other than a medium heavy oil pattern, you will NOT like this ball.
Keep looking... I'm sure there's a 300 in one of those balls you keep buying!!
