Scott,
See this youtube video of a rescue exactly two years ago:
http://www.youtube.com/watch?v=QsW050TIsv8I've uploaded two pictures from my trip that year as well:
http://www.whitneyzone.com/wz/ubbthreads.php/galleries/28623#Post28623The first one is from the west side. The second one is near the top of Trail Crest.
We had a sh*t load more snow at that time than this year. I was lucky enough to meet a marine who I was able to hike with that day. He carried an ice axe and it never came out for him to use. Both he and I only used our trekking poles. There was hardly an consolidated snow to sink the axe in or for the crampons to bite into. There was a lot of postholing going on. I still remember when we got near the summit, we started boulder hopping every opportunity we got to avoid sinking knee to waist deep in snow. Your crampons will most likely be kicking powder much of the way.
The Micros aren't great for steep and hard snow because those spikes simply aren't adequate enough like the front points of your crampons. However, they are great for mild grades and icy trails. I brought crampons on that trip, and the marine brought the Micros. The crampons didn't give me any advantage over him, and I only had it on from the Trail Camp to Trail Crest. I was crawling back to the Portal at night because the entire trail was iced over, but only a thin layer. You'll be tripping all over yourself with the crampons and grating all over granite the entire way. It was faster and less dangerous IMO to simply slowly walk on the icy patches or dodge them when I could.
Of course, this is all just my opinion.
