Got a good deal on völkl revolt 87s 177cm last season. Rode them 2 days and sold them. The 177cmm model is closer to 173 in "true" length and they were way too short for my liking. Also stiff ass hell, you need to have solid ground to get most out of those skis. Look into revolt 95.
Now i have this years Head oblivion 94 at 184cm, same length as my previous k2's at 180cm. Have skied them 4 days, they look like shit imo but i like how they ski. Had Head caddy 177cm, same as oblivion 84, few years back and they were also fun to ski on. Much easier to spin on 177cm, so maybe go with 177 94 or 84.
