Nice pictures!
55 lb backpack is serious overkill though, I can't imagine how you even got that much. Since you don't need to bring water, it should be entirely possible to keep it under 30.
And I'm not so sure that you had AMS. Your rate of ascent sounds too slow for that. I'd think of plain and simple exhaustion and hypoglycemia after spending 3 nights on the mountain. You need to load on carbs before the trip, and you need to force yourself to eat as you go.
