OK, I don't mean to be a pain in the neck, but in light of yet another fatality in the currently icy socal mountains (terribly tragic and my condolences to the man's family)...
http://www.pe.com/articles/hiker-795011-baldy-month.html... I feel like revisiting my old rant about trekking poles and microspikes vs. crampons and an ice axe. It is my personal opinion that if you find yourself reading, writing, or considering thoughts like "trekking poles required" or "microspikes required", then what you really should take to heart is: "crampons, ice axe, helmet, and the skills and experience to use them are required". Part of that experience is the ability to make the decision to turn around and bail at the right moment.
Trekking poles and microspikes are nice conveniences, and I use them on icy trails when there is no exposure to a dangerous fall or slide. I can really move quickly with them compared to wearing crampons, and that's nice. However, under no circumstances would I ever describe them as required. If certain pieces of equipment are "required", to me that means that those items are likely to come between me and an untimely demise and a few 1cm dull metal triangles just aren't going to cut it. Neither are floppy, non-load-bearing trekking poles that aren't worth a crap in a self arrest situation. Specifically, right now in the socal mountains, there's a beautiful and deceptively treacherous topcoat of glossy ice (no longer snow!) that is taking a lot of people by surprise and has caused 3 people this month to slide over 1000 feet to their deaths by blunt trauma, and many more to be rescued, so heads up. To me, slope + ice + exposure = mountaineering, not hiking, and there is no substitute for the proper tools and experience to prevent half the mountain's trees and rocks from beating the shit out of me.
With all that said, maybe you won't find that kind of exposure on skyline, maybe you will for only a brief section, tempting you to go for it, your mileage may vary. I don't mean to pick on anybody either, apologies for any bent feeling or comments taken out of context. These are just my thoughts and part of my heuristic system for making choices in the mountains. Make your own decisions and have fun.
