Climbed solo to the summit. Very enduring route!
Water can be a problem regards trying to keep hydrated. Carry more gas or Extra water rations...???
Route finding can be problematic up to about 3660m especially if you encounter early morning verglass.
This is a huge rock but all in all it's a great face puzzle to solve and certainly not as horrid as some have suggested in the past.
Climbing solo I reached Pt 3668m, but with the exposure climbing alongside the north face I chickened out of the last 300m and descended.
Nonetheless, for me this was a landmark climbing experience, bringing me out of 'semi-retirement' - and setting me on course for successful solo ascents of a number of alpine peaks and finally the star prize of Aconcagua in 2011.
