I realized in my previous post I neglected one topic: water.
Prior to the trip I believed it was better to bring up (and down) too much water than not enough.
I have changed my mind for two reasons. Water is heavy. And water or other liquids can easily be purchased along the route.
The two of us carried 2 x 2L bottled water, 2 x 1L bottles filtered tap-water, and 2 x 500mL bottles of amino water (tastes like a sports drink). This was a total of 3.5L per person.
We drank about 2.5L per person and returned with one of the 2L bottled water unopened. Cleaning up today I realized how much extra weight I carried around, and my shoulders felt it.
We found the amino water more refreshing and drinkable than the pure water. However, I would feel uncomfortable without some pure water. Most hikers can safely get away 2L per person. If you find you are consuming more, you can easily purchase more anywhere along the trail, including the summit.
However, be careful on the descent, because there are fewer shops along the descending trail.
Below is a non-Flash version of our experience.
