^While it may be true that you get the fastest acceleration straight down, it's the air-time of the over vertical drop that I personally like. Mavericks drop in the back totally over-shadows any vertical drop in the back IMO, and I have ridden SheiKra back row, and Maverick's drop is so much better. I even think Fahrenheits drop is better because of the airtime.
Again this is just my opinion.
EDIT: A bit more on-topic, I would love to see B&M try a past vertical DM, it would defiantly make a holding brake in the front a lot scarier not really seeing the track.
