if you want a ski that can jib, rip in the pow, AND be good (and not just doable) in the groomers/hardpack, then you should probably consider the armada jj, and you could probably get away with it on the rossi s7 though the tail is a decent amount narrower than the tail so i don't know how well it would ski switch though i've seen videos of it being done. The only other ski that i can think of that will do all of those is maybe an atomic thug (no rocker but still fun as hell), and the bent chettler is prolly too small for you.
line mothership and skis like that which are heavier/stiffer with only nose rocker are great for ripping big mt., but not so great for jibbing.
personally i think the s7's would be a kick ass ski, and they are making it in a 195 this year. i'm sure they would be sick, but pulled some triggers on some on3p wrenegades.
