I've never been one to trade just to have shiny & new. That being said, I seem to notice the vibration in my 009L a lot more than I used to, not the saw, just me. I only use it for limbing in the woods or trimming around the lawn. My MS 310 handles most firewood duties beautifully. Am I going to notice a significant improvement in vibration with a new MS 230 over my current 009L? I say 230 only because that the current CC equivalent of my 009L. Thanks for your opinions.
