I'm looking for something similar as well. I'm looking for Rocker-Camber-Rocker boards.
NS are all CRC and so are lib techs.
Rome has one board thats RCR, and Burton has the hybrids that are all RCR.
Ride Highlife UL, Ride Berzerker, K2 Slayblade, K2 Turbo Dream, Rossi Krypto might work for you. All have some element of camber or flat camber between the bindings instead of rocker.
