Everything you mentioned but the Rev 4 is a bow lifter, I'd hold out for Fr Franks opinion, but I think you skip over the the Bravo series and the semi-cleaver and jump into the cleaver category. Get the rear end up in the air, keep the pointy end down, "bend the throttle and let 'er eat" as has been oft repeated here. I have never run that fast so this is just theoretical not my experience...Heck I don't even like to drive that fast
