Ok so just a quick update on my 5'10" MB (thicker model). I've had 2 sessions and so far so good. It definitely was a drastic change from my 5'10" DM to a 5'10" MB but 25-30 lbs lighter in weight was drastic as well (i.e. 195-200 lbs down to 168lbs). So my first session I was a bit worried on not having enough volume.....but after my second session all is good. The board is super responsive. Not to mention paddling back out from the inside through clean up sets is actually easier......so paddling with less volume was actually easier.....does that make any sense? So basically I'm super stoked on this board!
