I think the 182 will feel small to you, but it will be quicker easier if the trees at your mountain are really tight. While there is not a ton of tip rocker there is definitely a noticeable amount that really helps initiating the turn... If your a good advanced/expert skier and your trees are not 'east coast' tight, then I say go with 191.

Jamey,
What if im an advanced intermediate who is solid on piste, but new to the back country?

Chris, I'm thinking the 182 might in fact be a better choice. Nothing worse than having skis you can't turn! I think you've probably got 1 or 2 more seasons on something in the low 180s and then you'll probably want to go longer. Hope that helps! -Jamey
