I'll go ahead and say it would be hard to ski someplace like vail without poles, but for park, I like to ditch them.  It makes it much easier to get your grabs.
Also, if you think it looks ridiculous, you are 100% right.  Just watch the Baker section of Idea again.
By the way, next time you ski powder, leave your poles at the top for a run or two.  It's different, some people say harder, but it's a good experience to try.  Really can be fun.
