This SF series was a total game changer for me. I’ve been loving North’s new high aspect series for winging because they are insanely fast and the pump power is enormous. Didn’t think anything could trump them. But these SF are so rippable to turn, you can stay right in the pocket of power on a wave, even in onshore wind-swell conditions like we get on the Great Lakes. This overall package that still provides crazy pump power, decent speed, with a shorter wingspan, all equates to a wing that’s easier to push critical turns, and ultimately more fun to ride - especially when you consider the ludicrously low stall speed that North’s engineers were able to achieve in this wing series. With this early rise / slower stall speed, I can now ride much smaller wings, which means less drag, more speed, and more control (to avoid breaching) with rapid accelerations on waves. I’m 200+ LBS, and initially I wasn’t even going to purchase the SF930. I’m so glad I was encouraged to do so. It has quickly become the only thing I ride in bigger swell. I’ll certainly be adding these two new smaller sizes to my quiver - the SF830 and SF680. I never thought I’d be riding foils this small and agile. The high aspects wings are still a go to for downwinding and flat-water pumping, but the SF Series is now my only choice for prone and winging. Kudos to the folks at North.
