In reply to AskeLanger:
Could you be more specific about your plans?
Alpine summer can mean many things. You could be scrambling at <2000m far from a glacier, or up on a glacier at >3500m. The former wants a lighter and cooler boot than the latter (you might even get away with an approach shoe). If you were aiming to do some high altitude ice routes (on the rare occasion those still come into condition in summer), you would want a sturdier boot and probably having a toe bail would be a hard requirement.
Scottish winter can also have varying requirements. I'd use a different boot for an early season romp up curved ridge than I would for climbing an ice gully on the Ben during a deep cold snap mid-season.
Your personal requirements might also make a big difference to your boot selection. If you have narrow feet, then two big Italian brands will probably work well for you, but if you have very wide feet you might need something else. If (like me) you have terrible circulation, then you might make the sacrifice on weight and dexterity and use a much chunkier boot. If on the other hand you don't feel the cold in your feet you could go for a super-lightweight boot.
I expect you are looking for a "do-it-all" boot that's a jack of all but a master of none. I believe La Sportiva Trango Extremes are the traditional workhorse boot. However, if it were me shopping, I would take a long hard look at the Trango Ice Cube.
