The 11 inch will have an easier time getting your ambient up without creating a super hot spot. Which orientation will the heat run on the tub, long ways or short ways. If it is longways, I'd go with 4 inch.

I figure why not? I don't think 32 quart will save me much money and I'd like to put some fake plants in their tubs. Also, it would be easier to sell way down the road.
