Any ski responds to the energy you put into it. Skis, in any manufacture's line, are made softer as they're made shorter / stiffer as they're made longer. Go too long, get too stiff, and the skis need more energy input into them to respond. Go just right and the ski responds at any speed.
I know the Head line better than others, so here's this--the Head Prestige:
"Style, performance, and timeless design are the key elements of our thoroughbred Prestige. It is a high-end ski thanks to our performance-enhancing Intelligence CHIP technology. With stability, speed, and agility, the Prestige also packs Metal Power Tubes that deliver perfect edge-to-edge power transmission and grip for an ultra responsive and energetic ride."
Sounds like a banker & broker ski.
I'm on the Head Supershape Rally on groomer days, and I really like this ski at all speeds. I'm 180# on a 170 cm.
