How much would micros-pikes need to be taken off and put back on.
Crampons are great for kick-stepping up steep, solid snow fields like the Chute (MMWT) and Gully (MR). Hard packed, boot tracked trail with mixed snow & rock is actually where micro-spikes excel.
I don't if micro-spikes were designed to be walked on rock, but no one I know (including myself) ever takes them off until you've obviously gotten below snow line. If you did, you might average .25 mph due to stopping every time you came across a patch of snow or got back out into some clearings.
On the way up, once you put them on, keep them on (unless you come across a completely wind blown clear area like the summit plateau). On the way down, ditto: keep them on until you take them off after you've passed the last of mixed snow/ice.
