Make sure to choose a board that has a smaller width at the binding inserts. If you don't want stiffer boards then you don't want a board like the Rome Anthem. The Lotus is a great board, but VERY stiff.
If you like a slightly softer board, the Vinyl would be a good choice and it probably comes in smaller sizes as well. If you are looking for a softer reverse camber deck, consider the Gnu B-nice, Gnu B-street, Roxy Eminence, Never Summer Infinity, Never Summer Pandora. I own a B-street and love it. Just enough stiffness to make it stable all-mountain, but you can take it into the park as well.
