Replying to Mr. Pollards Opus 2013

So im about to order the 2013 opus soon and am curious to what peoples opinions and thoughts are about it. from what ive heard and read on the interwebs its a great ski that rips it up all over the mountain (minus park of course. If i dont get the opus i am thinking of ordering the ben chetler. Also, im 155 lbs 5' 8", what size should i get? I usually like a longer ski but i think 185 may be too long. is 178 good? Thanks NS!
