Sorry to mention a hole so few of you have played, but #10 at Northland CC in Duluth (Ross 1927) is as good as I've seen for a non-returning 10th. Uphill, dogleg right par 4, woods on both sides, extremely fast green sloped from back right to front left, it's the perfect hole if you're down a couple holes in the match because it's so easy for your opponent to double. Conversely, if you're playing medal and you've had a decent front nine, it's the hole you know you've got to get past to keep it going.
Pebble #10 is a great hole, but it feels more like the extra last hole of the front nine, rather than the first hole of the back nine.
