if you're 150 and still want something nice and buttery, but won't fall apart beneath you, the atomic punx, k2 domains (if you like rocker, i think it robs a ski of any decent pop personally) or 4frnt clicks. these are not as cheap, but they're bomb ass skis that still have a super fun, softer flex, and are still lightweight.
switchblades are pretty stiff, afterbangs weigh a ton, i'm sure the filthy riches are dope, and i want a pair of ON3Ps more than any other ski, but price could definitely be an issue there, as it is for me unfortuntately. halos fit the buttery, lightweight bill, but they're again pricey (too much so imo) and i think the rocker is way too much there. again, lots of people love the rocker, maybe you would too, but the way i see it nothing beats a buttery ski with full camber for pop.
so, maybe buy one of those, hope it helps in some way.
