I'd still do 6, or at least set up a balancing system that will bleed the extra voltage off (diodes would be best).
Also, I have the strangest nerd boner right now.
Edit: Keep in mind that your over voltage figures are assuming that each cell charges equally; this will never be the case, unless you have some seriously high current capable balancing electronics.
