I rode a Slingshot Asylum 138 this rne comfy week, loved it! Its so much better than a Shinn, Mako, Epic,keep going... And it was green!!!!
I was totally stoked about the green Slingshot boards and bought a 2012 Misfit and hated it.
But I think their boards are very good for some kiters and I like what I heard about the Asylum.
I think the Asylum is in the same class as my Wainman Joke.
Surely don't think the Asylum would provide what the OP asked for though.
I was just trying to be funny. I did ride the Asylum a lot this week and was pleasantly surprised by the feedback I got from it. Very smooth,surprising upwind when marginally powered,but the stiffness is very noticeable, hence the great pop.
