Like others posting, I will be hiking Whitney via the switchbacks soon and am anxious for information on conditions, particularly at the infamous cables and any other trouble spots, as well as for advice on gear.

My permit is for June 28. Day hike with my adult son.

I realize conditions will be changing over the next week, but I am flying out from Vermont on 6/23 and 6/24 will be my best chance to buy any gear I might need, so I'll have to make some decisions ahead of time.

I plan to take my ice axe, but not my crampons. I have traction devices - one pair StabiLicers, one pair Diamond Grips (made by YakTrax, I think). Will these suffice or should I buy microspikes?
I plan to pick up an ice axe for my son and then was thinking of getting one pair of hiking poles, so we'd each have an axe and one pole at the icy spots. I have never felt a need for poles, but looking at the photos posted here, I can see how they might give an extra sense of balance at the difficult spots.

Of course, it would be great to not have to buy anything or to carry the extra weight, so if anyone can tell me that it has melted enough that gear is not necessary, it would be great to hear that.

Opinions? Advice?
