I'm planning a thru-hike of the John Muir Trail this summer and need to plan at least a couple of longer distance hikes to train and get used to longer distance backpacking. Since I live in Northern Virginia, SNP seems like a great way to do this in a location not too far from civilization (Skyline Drive). I have the PATC guide to the AT in SNP and am considering a northbound section hike but I'm unsure about timing. Ideally I would want to go in the Spring before the weather gets too hot. Since there won't be any shelters or huts on the JMT, I want to use my tent as much as possible rather than the shelters along the AT. However most of what I read seems to focus on staying at the shelters or camping nearby.
The following trip plan published by SNP seems appealing in terms of distance per day and camp locations:

Does anyone have suggestions on altering this trip plan in any way or the timing of the trip? Also, is Northbound or Southbound better? The logistics are somewhat easier for me Northbound since I would probably rent a car at Enterprise in Front Royal and drive it back home. To get to Rockfish Gap seems like an easy train ride down to Charlottesville and a possible hitch/shuttle up to the trailhead.
Thanks.
