I would say, only get 2x2s if you plan on getting a two channel or four channel charger. If you want to get that 10 amp X1 charger, I would get only 4s batteries. Drive it for a while before you decided if you want/need a 6s.
I do have a 6s pack - a Thor 500mah, 50c pack. I have only used it about 4 times. I think I have broke something every time that battery gets dropped in my car... LOL First run with it, bent rear shock tower. Second run, broke wing mount. Third run, tire exploded. Fourth run, broke neighbor's mailbox... HA!
