Replying to Line Mr. Pollard's Opus

I'm 16, 5'5, 135lbs and a fairly aggressive skier. I'm looking at a new pair of powder skis, and from the research I've done I'm pretty set on the Opuses. The only concern I have is that I'm looking for a super playful, jibby pow ski, and the Opus doesn't come shorter than 178, which I think might sacrifice a bit of that playfulness. If you have any suggestions on skis I'm open to those as well, but I'm mainly wondering if 278 would be too long for me.
