I ride a Ruby Expert compact, and compared with the standard cranks of my past bikes, it's like a whole new world. On the Ruby, the rear cogset has a low 27t gear and unless your hills are killer it should work ok with the double. I'm 49 and carrying an extra 15lbs that just won't go away- but I've been hitting the local hills and am getting up hills that I had to stop on a few months ago. So I would say a compact is doable, and they weigh less too. Just be honest with yourself and your abilities and you will end up with a bike that works with you and not against you.
