I've done both front and back- well, the front. With the rear I finally got it off after a long hard battle and decided to have the shop mount the new tire.
I just did the front for the second time two days ago. It was hard for me, but based on your experience changing tires you may not find it too bad. MotionPro BeadPro work great breaking the beads and as tire irons, btw.
Trust everyone who advises you to leave the rear tire to the shop.
