You are spot on Eric, a convex bottom, and also round edges, and a tapered outline, and to some extent more rocker - will make a board smoooooth and able to ride in the hardest chop without you feeling any of the usual bumps like riding on a rocky road
Such a board is the complete opposite of a typical TT or Door, as they are flat and square and sharp - these are a PITA in chop, compared.
But the "price" for chop eating boards is high, at least above design features will make you lose performance, meaning they dont go as early, they dont go upwind as well, and they have to be bigger/heavier to do somewhat the same as the square ones.
The good thing though, about typical chop eaters is, they carve like a dream, smooth and easy and they never catch the chop waves like the square ones
In general of course - there are some design wonders and dogs too out there
