Well-tuned, stock ms 260 Pro 16" bar & really sharp chain for everything w/ms 210c as backup. Average tree dia.: 10-18" on 10 wooded acres. Dealer recommended the smallest pro saw that would get the job done and just get through the larger stuff as it comes along. Above 24" dia. is a chore, though. I touch up the chain w/ every tank refill and like not having to deal with a bigger chain. I'm 5'-9", 160 lbs, 63 years old so saw weight and age are issues, but I can run the 260 all day when I need to. I feel this is an efficient and satisfying setup for me. Anyway, the felling, limbing and bucking work is pretty easy and takes a fraction of the time compared to hauling, splitting and stacking the wood.
But, I go to sleep every night thinking about how much better it would be with a 60-70cc saw. :msp_smile: ms 362, ms 441c, or 562xp would be sooo nice. My 2 neighbors have 100 acres of land between them and we're working on a deal where I cut the wood, they split it and we divide the firewood equitably. If this comes to pass, there are Stihl and Husqvarna factory-trained dealers within 1 mile of where I live, so I got great choices. Checked out the 562 and my wallet almost jumped onto the checkout counter on its own... Stihl dealer has been great, though, and has performed a number of adjustments on my saws at no charge.
