Also, and it's something people keep forgetting about, the one place where height really matters compared to board length is that a shorter board will have holes positioned for a narrower stance. Get too short of a board and you may not be able to position your bindings far enough apart to be comfortable. Pretty sure this requires more than a 6cm difference though.
In retrospect, "Let's get the goat drunk"
should have been my cue to leave the party.
