I use two saws, but then again I was lucky, I didn't have to pay for the expensive one. My buddy gave me a Stihl 460 magnum. I use the 460 to drop them, the farm boss to cut the limbs off, and the 460 to cut the trunks. My father in law and I have a system for cutting our "firewood" (oak only). I drop them (460), he tops them and limbs them (farm boss), and I saw the trunks to big wood stove lengths. We droped and cut three 50-60 red oaks a couple of weeks ago (few limbs though) in a couple of hours. We are amatures, and only cut for heat. After a couple of hours, you know that you have been running the 460 though. It is heavy, but cuts a trunk twice as fast as the general purpose farm boss. I cann't remember the model number, but there is a Stihl that is a commercial grade anti vibe saw, that is the same size as the Farm Boss for a little more money. That would be the saw if I was only getting one saw. Like I said, I got lucky in that my buddy gave me the 460 magnum, this is an expensive saw.
