For an all around axe my choice would be what we here in the US call a Boy's axe. It has a handle of about 26-28 inches and a head weight of 2-2.5 lb. My favorite production one is the Council Tool Boy's axe.
That being said, if I am going into the woods alone, I usually bring nothing, or at most a hatchet. I find that I keep my fires small, which requires very little wood processing, making the weight of the axe hard to justify. If however I was going to be in a camp with other people, the the above axe would be my choice.
