GB SFA for me. I don't know why you want to jump in size from a hatchet to a much larger axe.
I haven't handled either, that is why I asked. My 12 inch hatchet is too small for the job. I am thinking the heavier and longer model will make for easier work and still allow for one handed use. I'm leaning towards the 26 over the shorter 19.
I stopped into our local husky dealer but he didn't have any axes in stock. While there he said why no spoil myself with the GB that no one else would.
