Interesting kit. A few questions and ideas:

- going solo?

- what's the risk of a debilitating injury?

- how long before rescue would be initiated?

- how good is cell-phone coverage (any first-hand information)?

- add some heavy-duty painkillers?

- add some sturdy leather gloves?

- suitable boots, broken in, should you need to walk any distance?

- bigger cup (one pint/half litre minimum) or a two-quart stainless pot?

- maybe dump the tube tent and add a 3/4 length closed-cell sleeping pad? a light sleeping bag instead of bivvy sacks?
