I never worked a woodyard, and usually had access to wood loading equipment of some sort or another, so I hardly ever cut big wood up into firewood size. If the customer wanted some wood, they sure didn't want the huge stuff, typically 8"-16" diameter.
I rarely flopped a tree for removal. I found it faster and safer to climb it and piece it down. Eliminates 'loaded' limbs that can snap back and mess up an unexpecting groundman. Even if I did flop a tree, I would use a smaller saw to brush it out. A properly sharpened 026 will limb out up to 12"-15" wood just as fast as a bigger saw, and a lot safer.
Once the brush is cleared out of the way, one man with an 044 or equivilant can cut faster than 2 men can load the wood. That handles everything up to 30" diameter (Which is as big as 90% of your removals).
If you are doing anything bigger than that, you are usually using a crane. Or at least a log truck or Bobcat or some sort of equipment to handle the wood. At that point you pull out the 088 or 3120XP and make 2 or 3 cuts, load the huge wood and stump, and clean up.
Most firewood guys don't want the HUGE wood anyway. They will take anything up to 30" or so, the biggest stuff goes to the dump.
