I'm getting into more and more stuff where my 28" bar is too short. I'll be cutting up another two big oaks tomorrow, and while I can get thru them with the 28" bar, a bigger bar would make things a little easier, I think. Particularly for the miles of 30" trunk I seem to be cutting some weekends. I love the 28" bar, but as a second bar, how big would you go? I know Stihl recommends bars up to 42" on this saw (85cc), but I was considering something closer to 36". Thoughts?
