Which Slingshot board for rails,kicker,boat?

Hey all

Right now I have the 2011 Response and I am happy about it, rides well and all. Just having a little trouble doing nosepresses, but I guess that is more my technique than the board? Anyway my Response is close to dying from riding it on concrete and stuff so..

Which Slingshot board would fit my use the best? I primarily ride cable and winch, but also want to start to take a few boat sets soon. I prefer rail riding, and would like to improve on pressing. Also I would like to be able to get a little more grip than the response so I can go bigger on kicker.

So I assume I need something with channels; Hooke, Kine, Newton or Whip.. Which one would be the eassiest to do Nosepresses and such tweaks on?
