The only risk of going too low is de-beading the tire. I'd say if you want maximum flotation with minimal risk of de-beading, then about 15lbs. Since you think you won't really need to air down, maybe 18-20 to really play it safe.
The dramatic footprint gains don't start until under 10lbs but then you're playing with fire.
