Thanks for the feedback, scottyroo! As I said, I am pretty set on investing in the Proto CT to continue on my park, jibbing, etc since that is a true twin. I am looking for a 2nd board as an all mountain cruiser to help me on the East Coast ice, and would also be able to get me around when I am in Maine. Just wasn't sure if I should jump into a flagship board (Raptor) so quickly since I am switching brands and adding the benefit of the vario side cuts. That is why I mentioned my interest in the SL.
The Proto and the SL cater to basically the same type of rider... you just get more features and tech in the Proto. If I were you I would opt for a Raptor for a board at the other end of the spectrum of the Proto to give you some more diversity. If you still aren't sure you want to go all the over to the Raptor, I would get a Cobra.
