I would likely skip fins & things to get rusty nail and golden spike. All of them is a lot of ground to cover. I know you could probably do it, but you would have to be heavy on the skinny pedal and not really enjoying the obstacles. Fins & Things is just close to Hell's Revenge. There really isn't much to either trail other than the hot tubs. Then you would have to head across town and out past arches to get to the entrance of Rusty nail. I guess it depends on how early you want to start and how late you want to run. It isn't worth burning yourself out.
The tow is rough but you are breaking that up a little bit with a stop in Colorado. Scenery wise Hells Revenge has a couple of good views of the Colorado, Rusty Nail and Golden Spike put you up with some great views, Moab Rim is cool. Really cool at night as it overlooks the city. Pritchett canyon is a cool valley style trail that leads you out to some soft sand trails and the dunes so you transition from the river up through rocks to sand. Some trails are more challenging than others, but all together you could run most of them in a mildly modified rig because your tires stick.
