i've said many times, if i only had 2 saws it would be 020, 044.
From there the prefrence would go to ground or air, large or small wood.
i think the '44 is very good power to weight, and can carry ya from a very fast cutting, almost unstoppable 16" bar, to treking through 5' +diameter with a 36" bar nicely.
Hang Safe, Cut Safer!
Why do you think they call it a life-line?
P.S. Heck, Dang '44 outwieghs me as it is!
But at least in the tree i can be taller than the 36" bar version!
