Big dude here (6'4" 280ish). I'm riding 194 New Life's and I absolutely love them. They are nice and stiff cruise over crud and less than ideal conditions like it's nothing. They have huge rocker, but are super stable and hold an edge very well. At 151/122/151 and lots of rocker, deep snow isn't an issues.
They are a really, really big ski, so if you are doing tons of tight tree skiing or generally like a smaller ski, at your size, I don't think I would hesitate to get the 184 (my brother has them and he's about 6', 180 and he love's them).
