Apologies for the late reply. Yes, I do have a few chainsaws, and I'd agree that they can be dangerous, but are very useful if used with care.
For the volume of wood that I cut, a chainsaw is pretty well essential. I cross cut to about 18" - 24" length. For stuff over 30" diameter, or severely knotted, I usually run a starter cut with the grain, about 3" deep, which I then 'throw' the maul into. Longitudinal cutting is a little bit more awkward than cross cutting, so best left to experienced users.
When splitting wood I usually cross cut a load of logs, then stand them up together, in a circle, so that they support each other, big diameter logs evenly throughout the bunch. Then I work my way in from the periphery, moving round the circular bunch. Stop and pick up /throw into the trailer as appropriate.
