If youre looking for a ski to make medium to long radius turns on - DO NOT - i repeat - DO NOT - get anything close to the shape of the 3V (106-64-94) in a 176... I have skied that ski in a 176 and it was the most unstable ski i think i have ever been on (aside from a rossi 9s 9.9 in a 177). It is a ski that is meant for slalom - not long turns. Going from my stock LAB GS in a 182 to the 3V in a 176 was the most horrible feeling i have ever had in a GS course... The 175 2V is a much better choice. It is also capable of short turns - i can get my 182's into a slalom radius if im going fast enough, so the softer retail 175 should be no problem turning. I skied on the previous 2V model in a 172 for a season - great ski, turned very tight though. I ditched it for the stock ski because of the turning radius. I kept over turning and double turning because i was turing way too tight in the course, but it was a great free ski. I would reccommend that you go that route.
Check out Corbet's - i think they have some hot deals on Salomon skis. Around $250 Canadian for an older 2V with a plate on it. That ski (97-66-100) turns at 17m, versus the 16m that the 3V turns at in a 176. The newest 2V 100-66-93 turns at 19m or 20m in a 175. Check them both out - i think you will be much happier on one of those two skis. The 97-66-100 model was sold from 2000 - 2002, and the 100-66-93 model began last season and has carried through unchanged to this season. Salomon race skis go on a two year cycle - meaning they change every 2 years, but they never change the GS and the slalom in the same season, they alternate seasons. So every season either the GS or the Slalom ski changes, but never both... trace it back a few seasons - you will see what i mean.
Hope all goes well, have fun on the ones you end up chosing.
