In reply to Brian Pollock:
I have a decent softshell I intend to wear the majority of the time and I'd only pull out the hard shell if absolutely necessary.
I'd mainly be doing mountaineering style routes with some rock and/or ice/snow climbing sections. Most likely around PD-AD.
Also probably some valley cragging, but I'd definitely take the lightweight shell for that.
So far advice seems to be generally speaking since you'd only be doing these routes in good weather, going light/fast may be favoured over planning for the absolute worst?
My only concern is the Montane Litespeed H20 is as lightweight as shells come. I don't imagine it could stand up to too much abuse but then again I'd be hoping not to need to test it.
