As per my post above, I think you are in a unique place for ski selection. Tall but light, you need a shorter ski for more generous flex, you don't want to go too short and sacrifice your sense of front/back stability and you are too heavy for junior skis - they just won't perform for you (maybe at first, but as you learn to carve well they will pig out on you - too bad because they are great skis and real cheap). Here's a ski that might do - a decent wood core model that should have about a 16m radius sidecut in a 160 - halfwayish between a slalom and gs ski. For you it will feel more like a slalom ski at that length.

Race skis.com (
http://www.raceskis.com/) still has some 1 year new-old-stock $325 - great price, but only 156s left, a bit short but that would be happy turning ski for you.
If I were you I wouldn't mess about. I'd just go for this year's model. They have them on sale for $550 and still some 165s - also a good price.
I've skied Salomon, Rossi, Dynastar, and Fischers and I think the Fischers are the best by far. Don't prat about with the SC, RCs etc. Go for the SLs - you won't regret it.
Cheers.
