I am curious as well as to how you managed to have a 30# pack with the big items you listed. I am also curious as to which peaks and the routes you attempted. The high peaks, while not very high by western standards are, as you stated, a strenuous climb. So my last curiosity is what backpacking you have done in preparation for these climbs. If you were on the ladders, you didn't choose the easier ones for sure.
