Said perfectly! I couldn't agree more.

The only thing I'd add (and I'll bet it's covered in one of the other resources Mouse mentioned) is that she really will want to lower her pack weight; 30 pounds, solo, for a weekend sounds like a lot to me, too. However, your description of what she does makes me wonder if she actually hikes solo, or if this will be done in small teams. If teams, then it might seem like gear-sharing would be a good way to cut pack weight. If she's sharing that UL2 tent, then maybe she could get someone else to carry it (or the kitchen, water filter, or some other communal gear.)
