The wood core on 2011 / 2012 has a faster more “crisp” flex than than the foam core Mako’s. Overall durability has also increase with the wood core.
2011 / 2012 Mako’s also feature additional offset strap inserts and fin holes (thruster on one end) that allow a mutant style setup. You can ride the Mako 140 and 150 in classic twin tip, or switch it up straps and fins to mutant style to maximize the boards down the line wave slashing potential. In mutant setup, the board is still comfy to ride “backwards” when taking a break from toe side.
