Replying to Calling all One Lifers

I've basically decided on getting some surface one lifes for my east coast "pow day" skis, but I'm torn between the 179's and the 189's. I'm 6' 135 lbs, and normally I wouldn't have any questions about sizing, but since the one lifes are such a weird ski, I'm second guessing myself. I'm leaning towards the 179's because I'm so light, but the 189's might be better because I don't think I'd ever hit the park in them. Plus, if you guys have any feedback on the skis, that's welcome too.
