Depends on your draw length and how you shoot your bow. If you have a 28-inch or shorter draw, might want to go with the 60-inch bow. If your draw length is longer than 28 inches, a 62-inch bow will be more comfortable. If you shoot your bow vertically, might want to go to the 62-inch bow for the longer sight window. A 3 1/2 sight window may blot out part of your target, depending on where you anchor.
Otherwise, there really won't be much difference between the bows in draw smoothness or performance. I doubt you would notice a maneuverability difference, but there would be a weight difference due to the different riser lengths. Some like the additional stability a heavier riser provides. Others don't like the additional weight. I agree with Ace. God idea to talk it over with South.
