I talked with a locla Brusnwick staffr who received both Ambush and VApor Zone before they went on sale for tests, and he was very impressed with the Ambush's great controllability either on a THS and a sport shot (his one has the pin under the fingers, but I am not sure about CG placement). This ball seems to be a good addition to high end stuff, when you either face spotty lanes or the stronger stuff is ...simply too strong, eiter burning up or jerking around.
The Ambush's coverstock must be pretty strong, I heard rumors that its base was Activator pearl, plus a light particle load. Therefore, being a pearl, it should be a very good match for 2nd shift leagues and late games on medium to medium-oily conditions.
Nevertheless, personally, I'd prefer the Impulse Zone to the Ambush. It is solid Activator base, should have even better grip and control and has the additional options of the asymmetrical core. Just looks dull, though.
I am not a fan of the BVP bell core, they do not seem to work for me (tested a Punisher and a Nemesis so far).
