You don't need a lot of CCs, but you DO need an oil pump that will provide enough oil to the bar. You may have seen a guy running a 32" bar on an 026, but that chain was not long for this world because there's no way the oil pump on that saw is going to keep up with a bar and chain that long. An 036/361/362 would likely oil a 28" bar, but I'd be surprised if they will do anything longer without an upgrade to the oil pump (which is an option). If you really only need to clean up a couple of trees (ie a one time deal), this is a pretty good option. It won't be fast, but it will get the job done eventually.
As far as the clones go, I think you're talking about the patents, not copy rights. Those patents have expired, just like the patents on the original circular saws, combination wrenches, electric drills, ect. People used to make the exact same comments about buying products from Japan. Now Japanese products are considered to be some of the highest quality products in the world. These days, almost everything you buy has something in it that came from China. The clone saws are fantastic for what they are. They are NOT an out of the box replacement for an MS660, MS880, 395xp. They ARE a great option for someone who occasionally could use a 70cc - 90cc saw, but doesn't have enough work for them to justify spending over $1K, and is not likely to EVER do enough work with one to wear out a new saw to begin with. I will say that I'd rather have a new Farmertech than an old Stihl only because with the new Farmertech, I'm getting all new rubber, where as with the old Stihl, at some point I'm going to have issues with the rubber cracking and causing air leaks. Been there, done that. I prefer not to start down a path like that again if I can avoid it.
