If you're looking for the shortest (least amount of climbing to get to Hesitation), take a right where North Gate and Tower meet. Take that down across the creek and take the next right at Aynes. That will take you to the Hesitation intersection (just past the Green Valley turn) and you take that to the top of Hesitation. When you come back, go the same way and then jump back on to Green Valley for the return trip back.
The main negative about this route, IMO, is you miss the great climb up Aynes and the decent that follows and you miss NT loop. Enjoy the ride!
