For "high speed turns on compacted snow" the new term seems to be "frontside" or "groomer" skis. They are narrower waisted than the current all-around/allterrain and powder skis, and closer to the old carving/racing skis of the 1970's & 1980's (with thicker/wider tips and tails).

I had the same issues when I first rented shaped skis - they chattered and were very nervous and kind of unsettling especially on the flats (coming from K2 812 (205) and Dynastar Course SL (200), which sound like the same era as your Dynastars.

Frontside skis aren't so easy to find even in good shops or at a resort, but you can find them on the internet and get a local shop to adjust them. Mine are still longish - 185 Volkls from a few seasons ago - and I'm only 5'10". A good front side ski should carve well, track well and be stable at speed, and slice ice like an old GS ski.

There ARE new skis that are stable and carve well, but these things go in a cycle, and ski cross and parks are today's popular thing (no Mahre brothers). I'm too old to learn too many new tricks (tried a rail at 50 years old, fell on my face twice (my teenagers laughing), and decided to go back to Bushwacker & Plunge at Telluride - steep, knee-happy (and face happy) groomers into town.

They still make pure SL and GS race skis too, but I don't have a good grasp of those these days.
