Hurley,
I was up on Mon. You can look at the pics posted on the site and make up your mind. Also, my trip report is up as well.
I thought there were places that were sketchy, especially where the snow was melting and refreezing in the afternoon, such as going down the switchbacks or the drop from trail crest to the Muir trail.
It it were me, I would say bring them and worst case scenario is you don't use them. I'm sure someone will have more pics and feedback from trips this week. A lot will depend on if any snow gets dumped up there this week . . .
