In reply to RJP:
Fit is really important, so you are part of the way there with the suggestion of the Arcteryx. However, you could probably buy an ultralight jacket (Montane Minimus? Needlesports?) and a winter heavyweight one as well, right now in the sales, for the price of that brand at RRP. I am personally weary of anything less than 40 denier but that might just be ignorance --- I want to try something ultralight but every time I look at them in the shops, seeing how thin they are, I hesitate. An ultralight could be used for cycling and running as opposed to pack-bearing activities, as well as being a summer just-in-case rain jacket. Something in the 600g range could be used for general out and about as well as all-day shitty winters. I think if you are really torn between weights then you might also be be limiting your approach to function. I wouldn't consider 'downgrading' to a single, lighter jacket, but 'upgrading to two. Get a lightweight jacket now and get a heavyweight jacket in time for next winter --- if you can spend as much as the Alpha FL demands, that is.
I never use more than two pockets either. I would also consider a smock design with a single pocket, maybe two (Montane and Crux, for example). Length at the hem is important also and the Alpha looks a bit short at the front, perhaps? Edit: I don't like the 2.5 (?) laminates, think they are called 2-layer laminates, as I found they DE-laminate after about 5 years of 'normal' use.
