Andrew Sewell would be a good choice! I've met him, and we have a common friend.
Dr. Dave Nichols would be my choice if I was a dictator, but I'm not sure if he'd do it. He answers email though
Dennis McKenna is very friendly also.
I've had some contact with eack of them, and Rick Strassman, although I'm SURE I'm not the only SPF member whose talked to him!
