Zach,
Would have made time to play with you but have friends coming in for the weekend and we are playing #2 on Saturday. As for your MP/PN decision I favor Mid Pines and have since joining MP/PN in 2009. MP certainly has the charm and the feel of a 1920's Donald Ross course and is strongly preferred by the hickory golfers for its shot making demands It is the home of the Society of Hickory Golfers final major of the year.
Prior to the renovation there was a decided PN bias by the members. Some would not even play MP. Since the renovation that has all changed. Tournament results have historically had MP playing a few shots harder than PN, in large part because of the greater subtlety of the greens and the attendant approach shots. It will give you a good game. Be sure to walk around the hotel and be transported to the world of F Scott Fitzgerald. This was the last course that Webb Simpson warmed up on prior to his US Open victory at the Olympic club. Enjoy whichever course you choose.
