Wavesaurus there is a whole thread of people answering this question-
www.seabreeze.com.au/forums/Stand-Up-Paddle/Review/X32/You will never make a decision if you listen to everyone on this forum. Everyone has a different angle on things and above all different skill levels.
Only you can ultimately asses your skill level for where you want to ride and which board is right for you.
No one can make the final decision but you and the best way to make this decision is to strike up a relationship with your nearest Naish dealer and get some face to face advice. As we have discussed, if you are unsure, always go for the bigger board.
Your not friends with BoarderPaul are you?
