Wokrs Geeat, less tiring than my older 310
Since I finally dropped a tree on my MS 310 (don't ask), I bought a new 311. With the grip isolated from the engine and chain, it is much less fatiguing. I have dropped tress up to 83 feet tall with my 311, cut them to length for my wood stove, and filled my pickup without straining my back.
At 68 years old, that makes for a VERY GOOD DAY!
When I needed a new saw, I was asked what brand I wanted - there is only one - STIHL !
