In reply to SARS:
Hi I don't climb in Scotland but NZ which would be similar temps i think. I'm a 5 2 female but a bit of a tomboy.
My main issues were warmth / Comfort related.
When walking in Women loose warmth faster when you stop so Snacks in pockets, and a consistent pace rather than lots of stops
A GOOD warm hooded jacket (That fits over helmet and racked harness) and gloves for when you do stop. Dry gloves for belaying. A themos Of some thing nice and warm Is nice too.
Peeing- Salopete type Pants meant you had to take your jacket off I prefer no shoulder straps so I can get my Pants down without stripping down and everything blowing away.
Stuff is the same weight Regardless of your size unfortunately. I like Light axes and leashless (warmer, easier to shake out if getting pumped) No height problems, face climbing so balance will help, the climbing itself shouldn't be a problem
Will Gadd wrote an Iceclimbing book and there is a womens chapter. He discusses Layering and Nutrition for temp control. I found it useful.
Back pack wise I can carry a complete set of stuff by myself, but I find a good fitting hip belt Important as I can take more weight there than my shoulders.
Keep her warm..I almost didn't go back after the first time.
