Right now I have a pair of '05 Metron 9's that are 164cm. I'm 5'10" and at the time I bought those, I was around 160lbs. Right now I'm around 200lbs (sitting at a desk for 2 years will do that), but I'm working on getting down to around 180lbs. Ever since I bought the Metrons I've felt like I should have bought the next length up from that, but overall I really like them as all around skis. I'm an aggressive skier, and I generally like fast sweeping turns at high speed. I'd like to get some longer, stiffer skis that would really shine at that type of skiing, and have my Metrons to work on my bump/off-piste skiing. I remember trying some SX:9's before buying the Metrons an absolutely loving them on the groomers, so I went looking for something similar.
I'm looking to buy some '07 SX:10 B5's on closeout, but I'm having trouble deciding what length to get. I found a deal on some 173s with Neox 412 bindings for about 480, and some 180s with Neox 312 bindings for 600. The money's not so much the issue, I'd rather pay an extra 120 and not regret my choice for years. From the research that I've done, it seems like at the weight I am now, both lengths would be fine, but if I can manage to shed some unecessary weight, the 173s will serve me better.
The only thing holding me back from jumping on the 173s is the regret I had going with the 164 Metron 9s that the shop guy convinced me into. I'd really hate to regret going with the shorter ski a second time in a row.
I'd appreciate any advice, thanks.
