i can get a deal on some 181 addicts, but im iffy on the size. I'm 155, 5'10. i ski the east mostly and i have foils for all mnt stuff (174). im agressive, but the addict is a stiff ski. any thoughts? and i rode 05-06 174 scratches last year (the stiffest the scratch has ever been), so im used to a stiffer ski, but not in a 180.
