A 60 inch bar is a double handful, no matter how you look at it, and overkill for the vast majority of tree work out there. That 084 far more often ran with a Stihl 41 inch bar and chain. And a truly powerful saw it was, outfitted thusly.
I wouldn't even think about trying to wield that powerhead without the full wrap, but perhaps that's just because of the way I was trained...anything bigger than my 361, I have 3/4 or full wraps on. Wouldn't quite know how to handle a larger saw without.
