Hey Lucky,
You'll probably like your Onslaught, but it does tend to snap! You have to be firm with your speed.
My first time OOB I used it on second shift condition. Long Lite oil condition with a little carry-down. Perfect for this piece. The craziest thing was...all strikes that I got had superb carry....BUT....the pins fell in X's. Yes that's right, I said X's as in strikes!! The pins would continually criss-cross each other and go down in X's. Hardly ever in just one direction.
I don't know if anyone else has had this experience, but it was the craziest thing I'd ever seen a ball do.
