Whatever the shape is for the Real Heavyweight series (specifically the 8.38 boards), it's PERFECT, at least for me. Only thing I missed about Dwindle boards was the shapes, they generally have a really nice consistent and even concave that's easy to flick but doesn't feel aggressive. I tend to favor more concave than less so I really missed that, BUT NO MORE. Prior, I'd found other boards had a distinct flat part and distinct "concave" parts, kinda like this: " \___/ " but obviously less exaggerated. Anyways, great board after standing on it once and messing with it lol
