My wife and I have day passes for the first week of June. We're planning on trying the main trail and switchbacks. We'll spend a couple days at altitude ahead of our summit attempt.

Need some seasoned opinions:
- Currently, how well marked is the Main Trail between Mirror Lake and the Switchbacks?
- Based on super-helpful pictures on this forum, looks like microspikes would be better than crampons for the switchbacks. Agree?
- Ice axes nice to have but probably not necessary. Agree?
- What pantwear do you all prefer? It's been 12 years, and the few other times we've done Whitney it's been Late June or later and we wore shorts to the summit...
