Up until now, I've been cutting a fair amount of wood (10+ cords through the winter) with your garden variety oregon chain on the MS280. I don't know the model numbers, but whatever they list for the 280 when you walk into TSC, Menards, Rural King, etc. Today, I have reached Nirvana in my wood cutting experience. Having read about them here, I picked up a couple of Stihl semi-chisel chains and fired them up on a 32-inch hunk of white oak I've been picking away at. It was like cutting through butter. Almost literally, as compared to my other chains. The difference was night and day, and has literally changed my outlook on wood cutting. I have been dreading getting through another 15-20 cords this spring (trying to get two years ahead) because it has been such a chore bucking logs. Now I can buck in a day what it used to take me to do in 2 or 3 weekends. I can't imagine what a full chisel chain would be like, but my logs aren't the cleanest and I figured it would be too much hassle keeping a full chisel sharp. Once again, cutting wood has become fun, and that's something. Thanks fellas!
