Doing testing tonight as well. I have a few options in mind for batteries. My Speedzone 4600 pack is 7.3oz and my saddles and 9.1oz. A little under 2.5 ounces. So I plan to try shorty slammed all the way back with 2.5oz taped to the back wall of the battery box. So I plan to try saddles, shorty, shorty at saddle weight
