Even though you already did it, a thought: If you are taking the time to go half-way, it is the perfect time to drain and refill the rear gear case. Not nearly as convenient with the bag in the way.
I may have to try the up/over method sometime though. If it allows me to leave the hitch on (removing the bolts that secure to the rear crash bars of course) than it might be nice.
