First chance I got to surf my 5'11 BD was luckily pumping, hollow 3-5 foot shorebreak with rare bomb sets.
First thing I noticed was the great paddle power. The volume under the chest makes this thing paddle like a log. You can get around a lineup or go to battle with a big current far more successfully than a normal shortboard of the same volume.
Performance wise the board holds very well in forehand & backhand barrels.
You can trust it on a late drop which is very important, it's stable and makes you feel in control of even solid unruley waves.
Fell out of the sky into strong offshore wind 2 times on my first surf, on waves that I didn't really want to eat it on, but it connected on the way down superbly, and ended up making both drops. Much to the credit of the really well shaped pulled in rails & double concave at the tail. It's stable in critical takeoffs and forgiving / very under control when you're at speed.
It lacks acceleration in smaller surf, it doesn't want to shoot out when you take off down the line or accelerate out of turns unless you've got a steep pocket, so it's not ideal for slop. But it's still "ridable" in any conditions 2-6 ft.
Personally I think it's best in 3-5 ft average and better surf, making it super versatile and relevant most days. Not quite the one board quiver, but it'll still be my go to when it's 4ft, glassy, clean and steep.
I've only ridden it with a couple of thruster setups so far but I am very exctited to try it as a quad. I think the shape will compliment 4 fins very well..
