see now, the assumption is all we cut is alpine timber, when most of what i cut is under 500' above sea level, maples, birch alder, cherry, madrone, popular, oaks we get it all here, just not as marketable as cedar, fir, hemlock, but it all gets cutGeez Louise guys, give it a break. Ad Hominem does nothing good to improve discussion.
Both styles of cutting are taught professionally by guys who are strong adherents to their preferred style of cutting. If you’ve taken or helped teach S-212 in different regions you are well aware of this. They both have merits, and also downsides. Ask some of the fire guys who went from the west coast to help in NC, TN and KY a few years back. Several of them got hurt, a few really bad. Both of you haven’t cut the same types of trees.
Conifers and even west coast deciduous trees in alpine and subalpine areas of the Cascades, Sierras and the western slopes of the Rockies are different than the short, fat trees found in the midwest, southeast and mid-atlantic regions of the US. They’re easier to control and judge lean and limb weight. Humboldts and back cuts work great, and the Coos Bay cut is great for leaners. You can argue all you want, but they just are. Deciduous trees here short, have large crowns and usually less diameter on the stump. The wood is more brittle, generally. They will split and chair on you. Cedar and Madrone will too. The simple fact of the matter is that the trees that are out here are different than the ones there and comparing things without having done both shows ignorance on both parties.
No one is the end all expert on cutting trees down.
so yeah...
