I've read the avg time is 17 days from West Buttress route.
I've spent a fair amount of time in ice and snow, hiking, and even tent camping with several feet of snow. But We have never climbed in ice.
I've always tied off out top ropes, being the one who ascended without and to set lines. But I have never set anchors.
I have hiked in formal clothes and dress shoes nearly a mile in a blizzard to rescue a young couple. I ended with hypothermia, but not hospitalized, and no frostbite.
I've spent hours (years ago) in -80F windchill and know how to catch one's breath in extreme cold.
I can hike 12-25 miles in a day with under 50lb pack, depending on terrain. I'd have to increase that load capacity.
Those are some strengths and weaknesses. I have begun getting into better shape again.
Our budget for both time and $$, would be tight, so that's why not looking for guide service or commercial expeditions.
Sure, you can 'buy' the summit with some of these expeditions, but that's not our style.
Elevation concerns me the most. Here in Western PA, most of our climbing is 3k and below.
I told my buddies that to train for altitude here, we have to do whiskey shots and hold our breath! ;)
That was a good link above, thanks.
