I like riding super soft boards in general and have been lucky enough to sample alot of them outside my own collection. I generally ride 155 and below and I've test driven soft boards that have been 160 and above and IMO, the extra legnth didn't stiffen up the board to make that big of a difference. To add any significant stiffness to a soft board, you'd have to add alot of length making for a board that would be harder to spin and slower to turn. Not a great tradeoff.
