Hi Steve,

I have a permit to Hike Whitney this weekend and I wanted your input. Will we need crampons or will mini spikes suffice?
Based on: http://www.mountain-forecast.com/peaks/Mount-Whitney/forecasts/4418
It says there will be a heavy snowfall on Thursday night / maybe friday... its changed this past week from 21" down to 16"

Would it be better if we wait to hike till the following weekend? Or will it just be worse ice at that point?
