Hi, I'm looking at getting a Naish Nalu 11' GT (6'4 tall and 97kgs), and it seems that these are two different boards, the GT has a square tail, slight point nose and channels on the bottom (?), and the GTW is a rounded tail, round nose and flat bottom. Is there any benefit or reasons for the two slightly different shapes? See the pics attached.
I'd be using this mostly flatwater noosa canals/river and small waves.
Thanks in advance.
