Stiffness: 1 being soft, 10 being stiff.
-Mod Rocker: 8
-Bataleon Boss: 5
-Salomon Villain: 4
-YES The Greats has a medium flex (didn't have specific stiff rating), it's a twin flex, made for all mountain and freestyle.
-Capita DOA: 5.5
-K2 Happy Hour: Couldn't find an exact stiffness rating, but it has medium flex.
I pulled all those ratings off of various websites that have reviews on the boards. They all matched up correctly.
As you can see, there's a variety of different stiffness levels in that list. My all mountain is a 5.5 flex and it is a MONSTER. Out of this list I'd HIGHLY recommend the Capita DOA all day long. You'll love it.
The DOA had high reviews too
