yo, just got myself a new pair of k2 extreme. was wondering, since the edge are slicing hard, how to tune them to jib. can i hit rails right away or do i manually use them or...what?
its a really quick job, just get a small file and go slowly and evenly along the edges. i do that with my park skis, but the ones i use in the pipe and on jumps i try to sharpen once in a while.
The extreme comes with a 1 degree base bevel out of the factory. You want a 2 or 2.5 degree bevel for park, also measure 15-20 cm from the very center of the tip/tail and go down the edge with a gummi stone to de-tune the shovel in each side of the ski (This helps with butters).
