Hmmm. The Bushwacker is what it says. Superior ski for exploring, trees, tight terrain, bumps, light to moderate pow, can still hold its own on the groomed. Very light on its feet, can be thrown around without losing composure. Good, reliable edge hold, obviously not like a race ski. You can really feel the flipcore design; it's like an accordion as you lay it over; engages more edge smoothly and seems to lengthen, then as you change edges, goes shorter, again in a very progressive way. Cons: You may or may not like the flipcore feel. Also IMO not the best ski for crud or rubble at beyond a moderate speed. Doesn't fold, or get weird, but front begins to transmit a lot of information. lf you want one, the new ones are apparently even lighter and easier, so you may want this season's. Buy it long.
Supernatural 100: Different feel. Not a Line guy, so a novel experience, and I only demoed one run. A very middle of the road output, not too stiff, not too soft, surprising edge grip for a twin-ish design, damp and composed without being lifeless. Not as easy to throw around (also 12 mm wider and moderately stiffer) in the bumps as the Bushwacker, but better in crud or chop, with some good pop if you load it. I'd call it a touch more fun than the Bushwacker, but not as precise carving. Really liked mid-radius turns. I've heard the topsheets chip if you blink the wrong way, but can't say personally.
Finally, with your background, and where you ski, I'd strongly recommend you expand your list to include the Fischer Ranger 90 Ti. Also great prices on last season's, better all-arounds for a light guy with racing experience than either of the above.
