For cutting hardwoods, I use the directional felling technique, pretty much like this video. I'm sure it will draw comments from the western loggers, but the sawmills around here expect the notch, and it comes off with the slab cut anyway. One advantage is that it allows you to cut nearly even with the ground.

If you are selling the logs, I believe that you'd be selling on the Doyle scale. That's what loggers here in Missouri use, and is the most common for the eastern hardwoods. It penalizes for smaller logs. If you are wanting to predict the amount of wood in a log, use the International 1/4" scale. Add 15% if cutting on a band mill, since the thin kerf will give you about that much more lumber. Here's a pretty concise description of log scales: Log scales
