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?
