I am a 5'10" 160 lb college junior guy with only two GS races of experience and probably 6 GS training days. I have been skiing quite a lot since the age of 5 so I'm a strong, aggressive skier with great technique (though not especially refined for GS).
For my first season of GS (two years ago) I raced on 174 cm Blizzard Magnesium WC GS skis. They were two small. So the next year I bought some 2009 185 cm (27m) Blizzard Magnesium GS skis from a teammate for $200. Unfortunately I broke them on only the second day I skied them. It was early season and there were only 27 in of snow. I hit an invisible tree stump underneath about half an inch of very light fresh powder at high speed. We only have two GS races per season and it was a busy semester so I didn't bother buying another pair.
Now I'm in the market for some new GS skis. I saw that I can buy the same 185 cm 2009 Blizzard GS skis for $139 new on Amazon. But there are also some 182 cm Blizzard GS skis on Ebay for about $300 with bindings, which I will sell since I already have suitable bindings.
So would you guys recommend the 182 cm or the 185 cm skis? The courses we race on tend to be pretty tight and my GS technique isn't perfect. But $139 is such a great price and I'm low on cash.
