Either of those boards are great choices for you if you choose the right size for your height/weight. I'd suggest the 158 for the type of East coast resort riding you'll be doing. They're similar boards, basically the K2/Ride equivalent of each other, albeit with some differences like harshmellow vs. slimewalls for dampening, etc... Can't go wrong with either.
