Brian I did the two settings thing for quite a long time myself, but I found the angled fence method in a Fine Woodworking article a few years ago. This is a great method because not every miter saw has the tilt function and it also eliminates the math, although you can easily find angle tables for compound cutting settings on the net to avoid doing the math, which is what I did.
Abbas I hope I will be doing at least some of that today.
