Just drilled a cobalt vibe last week. Pin above fingers on centerline. Very surprising ball. I can play direct with it on hooking conditions, but also scored well on flat long pattern. Key for me is that it never forces me to cover a lot of boards, even with my slower ball speed. Pin up above ring finger or even slightly toward center line is great for me.
Bowled very well with it on USBC team pattern last week. Also bowled well on a very demanding 42 foot pattern. Much better ball on flatter patterns than on house shots.
