Dave L, the Lookouts have double camber. This isn't an issue I addressed originally, perhaps I ought to have, as it's very relevant to the subject. More camber (bend between tip and tail) means better spring and faster kick and glide. It also means that setting the full edge of the ski is harder, as it requires very aggressive weighting. If your used skies are well used, some of the camber might be worn out of the ski, a good think for turning.
The Excursion is (IMO) too much boot for that ski. It would work well for turning, but would not be the ideal thing for taking advantage of the kick and glide efficiency on the flats. A boot like the Rossi BCX11 would be closer to ideal. You'd be able to make miles, and still crank some turns, albiet with a lot for effort and care than with plastic boots and single camber skis.
One of the reason the Guide and 10th Mountain (now Annum and Epoch) have proven so popular is that they have more camber than typical downhill skis, for more pop when kick n' gliding, yet still fall within the realm of single camber, so they turn good too.
While skiing ice is rarely if ever fun, my K2 Summit Superlights are better than manageable or bullet, I'd rate them as confidence inspiring (at very low speeds). They ski ice better than I do.
