Guys, the SX boards in the photo I posted are from the 2003 Slingshot Dealer Manual.
TBKS, the board shape is definitely not the Drake, in comparison, with the Drake being narrower, longer, and more round at the tips. Looking at them side by side I can't see it. Maybe the show had something different - I didn't go since we had a downwinder scheduled for that weekend.
The photos were of boards, too. There's usually last-minute changes, though. Since you're going to call Doyle, I'll wait to talk to them, myself. The specs in the Manual are definitely incorrect, with the SX having a wider shape as mentioned previously.
I was told I may see an SX this weekend. I'll find out more about that, too.
