Hi 2dogs, yeah that tree's about the average tree size thinning forests down here, about a 15-18" tree, here it's in the middle of nowhere and steep, 60cc stihl does it, 70cc more comfortable on the bigger ones, a 460 perfect for 20" stuff if you don't mind carrying lots more fuel/weight,(let alone hammer and wedges) I prefer the 036, uses heaps less fuel, probably only a couple of measly seconds slower than an 044, not all trees the same size, by lunchtime 250 is a good enough tally, another 250 in the afternoon, no real difference in numbers between the saws, the 70cc always good to have when things get gnarly, even those trees in the pic, I'd tend towards the 70cc depending on how rough the terrain, that tree looks like he scarfed it, got in a shallow backcut, but the tree sat back, now he's just putting in another notch on the other side to drop the tree effortlessly. I do it a hundred times a day, on the flats mainly, let the trees tip where they want to, but going by all the hacking on the front of that tree in the pic - well, does that operator know what he's doing or not? Then again, often a quick cut gives an indication of which way she'll tip, but all in all it looks like a bit amateurish to me
