Carlest, I just bought a BV about two weeks ago. Mine is drilled pin above the bridge, 5.5" from my pap, CG kicked right to almost 1oz and no balance hole.
I have never owned a burgundy pure and never seen one roll so I can't be of much help comparing the two balls. Is the burgundy anywhere close in reaction to the Black Pure Hammer?
The BV is not a weak ball. It get's great length and has a strong arcish back end. One would still most likely have to play inside with this ball on dry lanes. It's got a lot of back end! However it does glide thru the heads with ease and is actually very controllable on the back end. For me the back end reaction is a cross between flip and arc.
I see the BV being able to be used on light patterns and can be used on some medium. I really am floored by the performance of this ball. I can't believe it's being sold at the price point it's at.
I hope this helps you out. I would grab one if I were you.
