Thanks all. I did a complete remount of the seat and did my adjustments more "scientifically" and after just a few tries I think I have it where I want it. I think part of my problem has been that I'm trying to achieve a fit that was right for me a few years ago, but at 70+ the effects of aging seem to be accelerating lately and I'm just not as flexible as I used to be. So even though my seat seems "right" now, I might try a different stem to raise the bars slightly to make it easier on my neck when looking up to look forward.
