Two of us summited on Friday, June 5th. I wore micro-spikes from the cables to summit and back down to the cables. My friend wore Yaktrax and broke them both by the time we were done. Another friend had crampons, but needed to take them off when we hit the rocks and put them back on when we hit ice/snow. It was about 70% of the time from the cables to the top that was snow/ice. My suggestion is micro-spikes and poles to get up the switchbacks. Of course, this all depends on the weather and whether it melts or snows between now and your summit day. NOAA seems more reliable than mountain-forecast for the actual weather. Either way, enjoy your time on the mountain! I always recommend stopping in the Portal Store the day before and talking to Doug (store owner) and anyone coming down that day from summit. A wealth of information can be had from those who just summited!!
