The end. Really, do we need to go any further? Demo some JJs or S7's and then come back and have the conversation. Otherwise it just devolves to the lowest common denominator as evidenced by the threads below. Not trying to be a jerk here but look, you ski on Shaman. I ski on Shaman. This is like trying to have a conversation with a guy who skis AC40's about why the Shaman still rails it on groomers and is a good all mountain ski. Should the Shaman rail it? No, it looks like a cartoonist's interpretation of a shaped ski. But it does. Give something like a JJ or an S7 a spin and you will be finding yourself saying, "this just should not be happening...". Call it McConkey magic whatever, there is a reason most ski companies are incorporating some sort of rocker in the design. Part of it is marketing fad but a lot of it is because it works. Go figure....
In the end it's all about making a ski that does everything very well, no exceptions (i.e.- why you are seeing camber mixed with all mountain). We all know ski categories are a jumbled gigantic mess.
