i normally ride 176'' skis, -2 from core center and generally ride park. I now am looking at some new Powder skis that are 182'' [Sir francis Bacons] (they are the only ones in stock). Would it be wise to buy these or do you think i should get a different ski thats more my size? Generally, what im asking is what is a good size for me for Powder skis given that i ride an average all mountain skis of 176''. Is it better to have longer powder skis or shorter.
