Heard alot about the CWB marrius. It is continuous but curves more at the edges toward the tip and tail (has rocker width wise in the tips) which i would guess would give it a little bit of a hybrid feel (never ridden one) Lots swear by the landings too. Anything that is three-stage (especially abrupt three stage) will exaggerate the bumps. Since the TRANSCEND is SUBTLE-3 stage... it might not be too bad (again, never ridden it)
of Boards I HAVE ridden, i think slingshot is great!, but i am not so sure if it is best for "slicing through" (or if there is any board that slices through chop but not the boat wake) the waves per say. All i can say for sure is that i definitely feel less "quivery" in the knees after riding a slingshot in chop. Also by far the SOFTEST landing board i have ever tried.
