Beautiful bird you have there, Mark!
I've flown mine (same exact color scheme as yours) at 74mm and everywhere in between there and 66. It flies and thermals great with the aft CG, but rudderless turns are just a tad sloppier, and penetration coming home from downwind suffered quite a bit. I much prefer it at 68 for overall performance and ease of flying. I also like a little reverse differential in the ailerons. Basically very close to the MMT recommended settings.
