not true at all. The mastermind is a price point, ski, and its also a piece of shit.First off, its cap construction, and the chronic is sidewall ski. The mastermind also has a shitty extruded base, the chronic has a sintered base for better wax retention. The chronic also has less sidecut, making it less "hooky" for a park ski. The mastermind IMO is for people who dont really ski park that much and want a ski that's forgiving and can still make good turns easily, and for cheap. (which the chronic can too, but differently). I guess you were right about the chronic being stiffer. Its just an all around better ski IMO, the mastermind is a crapshoot, dont bother.
On the way down its awesome.
