Disc Brakes or Drum Brakes

Since I am just getting started on my 69 Dart project I am probing the waters for all sorts of ideas. While I have a few immediate cosmetic things to deal with, I am also looking at some of the more mechanical issues. It seems that the front drum brake to disc brake swap is especially popular. I have read through a bunch of the threads including the 101 about this swap. It left me with my head spinning.

However, I was wondering if anyone is still running drum brakes all the way around on their Darts? My car is not going to be a track car; more like a street/show driver car. It is powered by a 318 with 2.02 heads and purple cam, and it is mainly meant to be a fun on the street car. Can I get away with keeping the drums and still upgrade to decent 15" wheels for my ride? Any advice or insight would be greatly appreciated.
