Rem -- that is a great, informative post. I made a copy, and will work in front of the mirror until I have a better understanding of the setup. You need to get busy and write a SA instruction book, it would sell like hotcakes. Not many good books on SA available. I had the Tom Sanders instructional tapes at one time, but just didn't get much out of them. Probably my fault -- good one-on-one instruction would be much more effective I'm sure.
