Whew, I found this post yesterday and have just finished reading all of it. Thus far this has been the most interesting and thought provoking thread I've come across. I have a 2010 SOP that I refer to often, even packing it out to the barnyard to assess and compare. I've thumbed thru the first 40 pages but will be reading that section now. I sure hope Mr. Miller can return to share more knowledge with us.
