The lunacy will be a lot worse for both spray and your knees.
i rode one for a season and its awsome for flat watter and small chop, any more than that it is easy to catch a edge and you would have to add swallowing lots of salt watter to your list as it will happens that quick you wont have time to think to close your mouth.
I do like the lunacy and stilll have it but really only for flat watter.
