Thanks all for your good advice. I had been leaning towards the 160 because I thought it would be a little easier to ski and further develop my carving skills. On the other hand, I can get the 165 for $100 less than the 160 (simply due to remaining inventory), and maybe the difference in length isn't that significant? If that's the case, I'd go with the 165. If it is going to impede me in any way, I'd rather get the right length ski at the outset, even if it costs me more, since I plan on getting a lot of use out of them. I've seen that some people on the forum who are taller and heavier than me ski the RX in a 165, though some of them are on the RX8, which I realize is a different story. Any further thoughts would be appreciated.
