In reply to Ant466:
We're testing those now and they're excellent. A bit flexible for proper front pointing (at least in my size 46.5) but very light, and nimble enough for year-round use. Nice to scramble in, but yes they're overkill for warm summer days for sure: All boots are, arguably! That's the sort of compromise you've got to make if you want a single pair for year-round use.
I'd call them a B1.5 in terms of winter capability so if it's mostly winter walking you're planning to do, or just easier winter mountaineering routes (I/II sort of ground) then they'd be ideal.
However there are loads of other options. We've got a group test in production now covering exactly this sort of year-round, all-round mountain boot (B1.5 / B2) so if you can wait til it's published late January then we should have answers to all those questions.
Here are the models we're looking at:
Hanwag Ferrata Combi GTX
Mammut Kento High GTX
AKU Tengu GTX
La Sportiva Trango Tower GTX
Scarpa Ribelle Lite OD
Salewa MS Vultur EVO GTX
Dolomite Torq Tech GTX
Kayland Cross Mountain
Some might be closer to B1, others you might call B2. It's an imprecise science, and I reckon B1.5 is as good a category as any.
I can't yet recommend one over any other - from what I've seen so far they're all good. It's what fits you best that counts most of course.
