I just received a brand new 2007 iSonic 145.. it looks amazing! But.. the fin supplied with the board is a Drake R13 52 NR Tuttle. The board has a Deep Tuttle box; is this the correct fin for this board or the shop gave me the wrong one? Should I ask for a Drake R13 52 Deep Tuttle (if existing)?
I'm too afraid of craking my brand new jewel..

Thank you for any suggestion.
Cheers
