The only experience with powder I've had (If you can call it powder) was when I went to Mammoth Mountain and I cut through un-groomed sections between some tree's. I fell once in the stuff and it was probably like knee high. That's what got me wanting to try and search for powder though, I liked the feeling of floating, compared to feeling like your on concrete when you ride on the hard pack groomed stuff. I ride a 162 lib tech now also, so I'm used to a bigger board which is good for powder right?
Haha... we all get hooked on powder. There is nothing better than carving through untracked fresh powder...nothing. I am a powder hound and can;t get enough of it.
This is typical of what you will find on the groomed runs in Japan. Hakuba last day
