In my opinion, it lacks the hit because you went too far from the Messenger pearl, a medium-light oil ball, to the V2 Strong, a heavy oil ball. There are many balls in between these two that would have been more appropriate. If you don't want to buy such a ball, you may polish the V2 up a bit to help it retain more energy, skid a little further before biting the lane and hooking. Based on your description, I have little doubt that the ball is grabbing the lane far too early.
Solid 7 pins indicates it is not high enough in the pocket to carry; not truly flush, although it appears that way.
I hope your pro shop did to recommend this to you, based on the Messenger being too weak, not strong enough to handle the oil. If they did, I would not trust them any longer.
