for everyone whos sayin invaders, you do realize the silencers are way stiffer? they are two totally dif skis.
as for you Q, the silencer is a fun lil ski. they are pretty stiff new, but soften up a nice amount as they break in, and have a ton of pop. they ski reasonably well all mountain, but they definitely dont have the edgehold of a full sidewalled ski. they are great little jump/park skis tho. i rode two pairs for two seasons, and while they werent my all time favorite ski, they were great for how cheap they are. K2s are always a tad heavy cause of the torsion braided core, but it also makes them bombproof. topsheets peel but nothing structural or anything.
the invader on the other hand, is much softer and a bit lighter. awesome ski, but for bein 190 lbs they are gonna be noodly as hell.
So, if your looking for a 1 ski east coast quiver, id get the silencers, or shop around for a better ski used. if your just lookin for a park ski to jib with, the invader might be a better choice. but being that your 5'8 190, id be willing to bet youll be foldin them in half. the silencers are still plenty pressable, and work better everywhere else
