I'm 5'10" and 150 lbs and ski reasonably fast, my other skis are a 175 cm Head iM88 w/ alpine bindings and a 172 cm Volkl T-Rock w/ Dynafits. These are set up with alpine bindings. I'm using a moderately stiff Rossi B2 boot.
The Watea 94 has the same springy, even-flexing feel of a good Volkl (I've also skied on Gotamas in 183) and very solid torsional stiffness for damp, deep, cutup snow. Not quite the metal-sheet feel of the Head Monsters but very close -- the stability is equal, the feel is just different. On reefed snow it quiets the rough spots. Carving hardpack is surprisingly solid and stable for this waist width, powerful edgehold. In new snow of up to 24" deep I've had a great time, no matter whether the snow was dry smoke or damp mashed potatoes. Outstanding ski that wants the fall line and wants you to get after it. Not sure how it would be under heavier skiers but it has all the power and stability I need at 150 lbs.
