Just a thought on bar length. I have an older Stihl similar to the Farm Boss you mention. I just went to the dealer and bought a 25 inch bar/chain for it. It saves bending at the waist while working, especially in deadfall.
Just because it is a 25 inch bar, does not mean you have to bury it in a 24 inch hardwood log. And full skip chain makes it more forgiving in that regard.
^^^this^^^ I use to run a stihl 049 or sometimes an 064 (don't know what today's equivalents are) on the fireline and for firewood. The longer 25" bar makes a world of difference for the good and doesn't really add hardly any more weight to the saw.
