I've got mine wiht the pin under the ring finger, and the cg kicked out a little as stated above. I haven't had a problem with it rolling out. In fact it's a nice, controllable arc on fresh oiled conditions. I do throw it with quite a bit of hand, and at 18mph, so you cna adjust as necessary. I was throwing it standing right around center, and swinging it out to about the 8 board, and it came right back in. I've thrown it once so far, with a 279 the 2nd game, and I love it as my new heavy oil ball. It's my first Inferno, BTW, so I really can't commpare it against the others.
