BBT just dropped them off tonight. Compared to 2012 EST Cartels, w/no adjustments to the Gas Pedal or Forward Lean on the Highback.
1st impressions: Base seems more solid and beefier in the EST slots. Highback torsional stiffness feels the same, which is odd given the '14s have more material along the sides. The new ones are definitely shorter than the 12's. Straps are nice & don't feel all that different (ReactStrap vs. 'normal' strap?), but I haven't strapped in. I haven't mounted them yet, so no real comparo on the hinge feel along the longitudinal axis of the board. And of course, this will be... in my living room, ollieing on a piece of carpet.
