I think the most similar to the Evo would probably be the Buck Ferton if you want the combo of rocker and camber. They make great flat camber boards too. I had the M.I.P last year which is probably a hair softer than the Evo and I have the Mail Order Bride this year (discontinued) that is a stiffer flat twin.
Thanks for the info buddy. I was looking at the buck ferton, but wasn't sure if the flex would the same as my EVO or be closer to the stiffness of my skate bananna whichh I didn't like. How is the pop on a flat camber board? I really like the pop that rocker/camber gives me with the catch free feeling of a rocker board.
