I just drilled a RAZYR Friday...ball is stronger than urethane.
3-piece core, strong reactive.
RAZYR LAYOUT, OOB surfaceI'm lefty, I used the ball on Medium Oil, rolled it up 5-7 board (down and in)...ball held pocket, very well.
I also had a Hammer Acid drilled up, same day...I had to play the Acid 14 to 8 on the same lanes.
ACID LAYOUT, OOB surfaceMy speed was about 16 mph, revs about 325-350, that day.
