In reply to Tricadam:
I have yet to find 'the perfect pack' for ski mountaineering, and always find myself modifying stuff. The climbing ones aren't great for ski carrying, and the skiing ones aren't great for mountaineering. I'm currently using an Osprey Kode 32, which is pretty good but I have had to add some gear loops and a second axe loop. I find by really being ruthless on what kit I take I can fit a day of ski mountaineering kit (including harness, some gear, and a rope over the top of the pack) in it. It's tight though!
In terms of edges rubbing; I make sure the skis are cinched well back. Maybe you could improvise with a loop of bungee cord running around one ski, around the pack, and to the second ski? Or a spare strap with a clip could be sewn on to the pack for this purpose?
I've never had issued with edges rubbing my jacket, just cutting through the pack material through repeatedly putting them on / taking them off the pack. I sewed on some thicker material at hot spots to counter this.
