Replying to ON3P SIZING HELP

OK, so, I am looking into buying new skis for next year. I don't plan on buying them just now, but have some options in mind when it's time for skiing.

My options: ON3P Filthy Rich or Jeffrey

My only dilemma is, I'm not sure what size to get because they are rockered. I'm 5'11, 175lbs and ski jumps and rails 80% of the time, and groomers 20% - would be my 3rd year of park skiing, but i've been skiing groomers since I was a youngin. Right now I have a pair of 09/10 Masterminds 167cm, but I feel like they are too short, as much as I love them I want to move onto a longer ski. I know there are like a million threads on this but I wanted more personal feedback.

+k for help!
