Yeah, I just got one of these babies. Pin over ring, MB in flip position. I pulled it out after my Vicious Pearl (my most aggressive skid/flip). Upon release, I thought I was going flush, but at about 48', it took a MAD left turn!!! Went a little left of head pin!!
I've throw hundreds of balls and this one has the most extreme backend reaction I've ever seen!! I love it, but I have a lot of hand, and could only get it to excel on carrydown...just too much for fresh backs.

When having trouble, just throw it harder!!!
