For the hard snow carving ski, you are going to get the most from a tortionally stiff frontside design ski. The two you've mentioned are good choices, I've skied them all. Of the Supershapes I'd steer you away form the Titan, but that's me. You can look at the Blizzard, Fischer, Atomic and Volkyl also. Others here have better resources to fine tune ski selection. Regardless of the ski you choose, assuming you don't go too soft, tune is very very important. DO NOT DO NOT DO NOT let the ski shop detune your ski "because that's how most people like it" The usual zip and dip tune also isn't going to do it. Let me put it this way: I'd rather have a race tune on a decent ski than a bad tune on a white hot ski. On hard snow, and we're saying "hard" in the East, you know it's hard... you want grip and you want the entire edge.
Then the bumps. That's going to depend on how you ski the bumps. On a stiff frontside ski, my .02 is you're going to want to ski the shoulders in a rounded track and stay out of the troughs completely. If you don't have that skillset, you likely aren't going to like a stiff carver in the bumps. Consider 2 pairs, one for each style of skiing. A real performer on hard snow, aka a beer league race ski, is going to be a handful in the bumps. You can relax the frontside ski, but you will lose grip and snap.
If you really want to improve your carving, find a ski that will not hold you back and will show you a good time on a so-so day.
