I can't yet speak w/experience to the plus part, but I often ride rigid on my local trails. For years I would ride rigid in nearby Marquette as well. You'll want to be off your seat a lot, and ride more like BMXers ride, letting the bike move under you. I actually prefer rigid for riding gravel roads and doubletrack. Does the Jones frame also give the option of front suspension if you want it down the road? It's a nice option to have.
