Just east coast? I'd say the Evo.
Since u didn't choose that, Proto
Unless you plan trips to J-hole and the like, the Heritage is just extra board you don't need, hence my suggestion of the Evo even. I'm getting one soon that will replace my Proto if the only thing we have to ride all year is a WROD like last year.
The scaled down boards will be more playful and fun on smaller mountains.
