Thanks SnoWolf!
Additional advice...
If you are super into park and dream of eternal park riding...then dull dem edges. Their over rated anyways. I mean, im hoping that your riding skills are strong enough that you can effectively ride some black diamonds with confidence...if so, then take that file to your edges. when its not icey out, you will only notice a slight difference. When it is icey...then i hope that you try not to ride park anyways.
(as my motto states)
Get comfortable with the uncomfortable...
