M.B. might be in the wrong spot.I had a T.F. with pin down and M.B. about 75* and it layed off on the backend.I think with the vibe you can add some more side rotation but with the asymetric core of the twisted that becomes less forgiveing and you lose the reason for useing an asymetric core ball IMO.
I like asymetric equipment because I have a very consistant release and I can choose how the ball will react down lane with drillings and covers.they are not as forgiving on release changes as symetric cores in general.some more,some less,depending on the strength of the core and layout.

The harder I try the harder they fall
