Pretty sure for #2 there'd just be too much "mud" if you turned up the mics that high. There's simply no way to get the kind of attack that you'd get at slower speeds, which means with the volume cranked it'd sound less like a clearly delineated line of kicks and more like a wash with pulses.
As flies to wanton boys, so are we to the gods. They kill us for their sport.
