I've had this board since 2016 (writing in 2020). It's the perfect HPSB for somebody who is used to riding grovelly / alternative shapes, and wants to get more maneuverability out of a daily grinder. Or if you're getting a little too old for super potato-chippy boards and pretending you're on the CT. This is NOT the board for pipeline. This is also NOT the first board somebody should try to surf on.
For comparison, previous board was sized about +1" and -1.5L, with slightly more pinched rails. The DX1 floats better, paddles easier, bogs rail less, and is generally easier to generate speed on *for somebody who is not a pro skill level*.
And for fins, this board actually got me to like more rake/sweep instead of having upright/pivot fins. In FCS this would be like a Carver or Accelerator (ie. Mick and Julian's templates).
Hopefully this helps somebody
