If you know Keith Sullivan, get in touch with him. He arranged a group trip there a couple of years ago or so. I'm been up Adams a few times, but not via that route. Have always taken the South Spur, sometimes as an overnite from the Lunch Counter, sometimes as a long dayhike. FWIW - been a good snow year for the Cascades and Sierras so far.
If you don't know Keith - PM me. I can put you in touch.
