I would pick BH! This ball just does more! i think a lot of it has to do with the surface attributes of the BH compaired to the VG. Seen a lot of success with the Vg, and great responses from the storm camp, however i have seen a few loose there luster or as others say 'have died'.
For me the ball is very angular off the spot, sees midlane friction and checks up hard in the back. It hooks a ton, at 4k, just makes me wonder what it would do at something with more surface.(2k,1k???) Never a hook stop type reaction with this ball, it just keeps going till it goes thru the pins.
