@rod9301: Exactly. BK's condescending comment, which is essentially telling you to "sit down and shut up", reflects one of the key problems on Epic: it's loaded with "keyboard warriors" that make remarks that are more snarky than helpful. If BK truly wanted to be helpful, he should have started by ASKING you about your background skiing couloirs, instead of making the ignorant and insulting assumption that you probably don't have enough of one. ASKING ticks all the boxes: It ensures a skier isn't being given inappropriate advice, and it helps make Epic a more friendly, less obnoxious place for people who want to post questions.
I have skied steep, narrow couloirs; here are the two divergent equipment choices that have worked for me:
1) A short (~160 cm) narrow, quick, soft (needs to be soft to bend in powder) recreational SL ski. This works when the snow is firm (very quick, good edge hold), and when the snow is deep but moderately heavy (you sink, which slows you down; sometimes you actually like to carry a bit more speed with these, to avoid sinking too much). It's not as good a choice when the snow is light, since it sinks so much that you can end up on the rocks below the snow if the coverage isn't good enough, nor when the snow is super-heavy (Sierra cement), since it becomes a lot of work to turn the skis under the snow. Plus, at least for me, there's something about the shortness and maneuverability of these skis that makes tight spaces seem less so.
2) A wide full reverse camber powder ski. Turns very quickly. This doesn't work well when the snow is firm (for obvious reasons), but is very good when you've got some snow depth (>~ 1 foot), regardless of whether the snow is light or heavy.
