Surprise: Roto Grip Mutant Cell. I took it up to 4000 before even rolling it the very first time, and as long as there is oil, it's a hard hitting monster. But once the oil goes, the ball goes back in the bag.
Disappointment: AMF Sideways. I just can't figure out this ball. Over/Under, weak hits. It's still OOB, so maybe I'll play with the cover a bit.
Still going strong: Sorry, just throwing this in.
Banger Hole Pounder Pearl. I been throwing this on the third game and on drier conditions, and with some fresh Bean's Sauce, this bugger still pounds the hole!
