Replying to What length Volkl Mantra M6?

So…I had a pair of ‘17 Mantras that bit the dust last year. They were 184s but I am questioning whether I would like a set of 177s if I buy the new model this season, since they have the 3D sidecut.

For reference, I am 5’10” 195 in my mid thirties. I’m in my thirties and sadly have a real job so I don’t ski as many days as I did in my youth, but I’m still strong and ski aggressively on any terrain (just not with the same stamina). I wonder if I was working extra hard with the ski length that I had.

So, do you guys think I should stick with 184s or switch to 177s?
