My double wide just showed up in the mail. I ordered a medium flex. And it's as stiff as, if not stiffer than a 10/10 stiffness production board. Can't wait to ride it in the morning. Will follow up. 

@keithdobberpuhl I got a mid stiff DoubleWide as well and found it way softer than expected.  This isn't stiff, if you want stiff I'll show you stiff...

Just kidding.  Longitudinally, this board is softer than the JJA C4 soft flex; torsionally it's way stiffer than the C4 though.  The next batch will be slightly stiffer longitudinally and softer torsionally.

It's not too stiff, don't sweat it.  I've been saying for years that production "carving" boards are way too soft so comparisons are not appropriate.

Ride it!  let us know how it goes.
