Sheng Pu'er Help!

Hi, Steepster!
As a present for a dear friend of mine, I was thinking of getting some Sheng Pu’er so that we could age it over time and see how the flavor changes. I am no master of Pu’er, so I would greatly appreciate suggestions or feedback about your favorite Sheng Pu’ers, preferences, etc. General Pu’er discussion would also be good!
