I'll say, that I wasn't throwing at 100%, because I had a really tough lower body workout yesterday, and I couldn't drive off the pivot foot, nor really get into my slide.

That being said, I will say this much.  For what I've bowled at the home center, while it doesn't have the skid/snap i expected (might have been the inability to pivot/drive), it acted VERY predictable.  I ran off a get-to-know-you game of 174 (1 strike, had a 3 spare lol), then a 10 strike 243, 279 (weak-ish 7), and a 224.  

Not a bad ball for the first time out!  definitely a good buy.
