The FDX-1 in AirFlex Technology - built to feel familiar the moment you step on your shortboard, the FDX-1 was designed as a balanced, dependable template that surfers can rely on day in and day out.

A single set of fins for every shortboard in your quiver.

AirFlex Technology combines a precision shaped polyurethane foam core with high strength fiberglass and epoxy resin, creating a lightweight internal structure supported by a durable outer shell.

By removing excess weight while maintaining structural integrity, AirFlex Technology delivers a balanced, predictable flex pattern with quick response and smooth feedback under foot.

“Freestylable,” says .

He continues, “The Parallax Plus is really freestylable when you’re dealing with 2 + 1 fin setups.”

He elaborates that there are generally two types of surfers when it comes to choosing a 2 + 1 setup for the Parallax Plus: those who have spent most of their lives on boards they surf off the fins—such as a shortboard, an egg, or a groveller—and those who want their board to primarily feel like a “juiced-up” single fin.

For the first group, he suggests larger side fins with a smaller center fin; for the second group, he suggests smaller sides with a larger center.

Specifics?

“Any side fin can be paired with any of the performance center fins we make,” he says. “The sides are a great place to start, as are any of the sides. And then you have my personally designed Skylimit sides.”

“This is an interesting surfboard… I feel like you could put a lot of different fins in this board, and it would work really well…” -

For the Oracle, the one rule is this: bias towards a little bit smaller of a fin than your intuition suggests.

CJ calls the Oracle one of the most important surfboards he owns. The culmination of years of glider experimentation, CJ transformed a traditional point and shoot glider into a well-rounded, performance driven longboard with versatility when it comes to fin pairings.

CJ pairs his 10’6 Oracle with a a 10 inch Involvement template, but your decisions are free to move about the cabin. 🛫
