Well done on the new board old Dave ..I had my 10 mana for just over a year ...before a friend pested me ..to sell it to him .dawn I miss it sometimes ..but I now have the naish 9.6 Hokua which does handle the narly reef break I surf ,a bit better....oh ..and a 11' Nalu .
With the rear fin in surf I found it better with the fin up forward about a inch of the front and just paddling around ,up the back is better .Dont go out in to bigger waves 5-6 foot ,as having 192 litres it does tend to try and pull ya leg off with the leg rope .
enjoy ..it's a great sport .

Mine was just the GT not the flash new wood deck like yours ..wow.
Tardy ..
