Absolute is an abrupt kick off the wake, soft landings, bites hard on edge finless. Very much an ollie pop board/wake to wake. Best board I've ridden.
Prodigy is a more continuous rocker, faster, edges like a b**tch.
Plat's are quite a bit stiffer = more pop but harder landings. A bit lighter = no-one will ever notice. Until someone makes a board five pounds lighter, this is a moot point.
