If you're not trying to ski switch or spin or otherwise have a playful ski whatsoever, the Volkl Confession is one of the best options on the market for skiing stupid fast in chop and pow. But it's a fairly niche ski — not easy to pivot, definitely not easy to spin, and overall feels best when you're skiing wide-open terrain where you can get it up to speed.
The Rossignol Black Ops 118 is the best ski I've used when it comes to being ridiculously stable in chop, but it's still balanced, skis switch well, and doesn't feel nearly as one-dimensional as the Confession. If you want a lighter, less stable alternative, see the 191 cm Icelantic Nomad 115.
If you want something that falls in between the Confession and Black Ops, the Nordica Enforcer 115 (used to be called the Enforcer Pro) is worth a look. It's slightly less stable than the Confession and Black Ops, but is significantly more forgiving and playful than the Confession.
The 190 cm Moment Wildcat also warrants consideration. Not quite as stable as the skis above, but way easier to flick around in tight terrain.
The Super 7 RD also makes sense and falls in the same class as the 190 Wildcat — not super heavy, but very stable for its weight. Probably the quickest of the skis I've listed, and I'd say it's a bit less stable than the 190 Wildcat, mostly due to its more tapered, hollowed-out tips.
189 cm J Skis Friend and ON3P Jeffrey 116 should also be on your list. The Jeffrey is similar to the Black Ops 118, but maybe a touch less stable and easier to pivot. The 189 cm Friend is similar to the Jeffrey in terms of stability, but probably a bit more forgiving.
Lastly, the DPS Koala F119 is a super stable ski that's still fairly playful thanks to deep-ish rocker lines and a -6 cm mount point. I doubt you'd be able to find it cheap though.
