What do you have?
Without sounding rude have you thought this through properly?
A 6' 10" Addvance is *nothing* like a 6' 10" potatonator/spitfire/dominator, you might need a slighter bigger Spitfire than a Dominator.
Long story short, each of these boards are unique, they all do different things and therefore you'd need a different size in each.
I'd suggest having a look at the volume calculator on the Firewire site (as it seems the only brand you're interested in) work out what litre board you need and go from there.
Of course, I could be talking crap so feel free to ignore.
