I did it just to get the feel of the shorter pole.
3" off the bottom, and re-drilled for the Pole bolt.
Was pretty easy, and free99, but temporary.
SN pole is still so heavy/prone to breakage. (I think they're made of cereal)
RN poles are so light, easy to shorten/make work on SN, strong,And super reasonable cost wise.. I paid $125 shipped for mine. I've seen a lot of em in the 100-200 range depending on yr, and inclusions..
I say if ur bored/time to spare/like free mods. doit. Ski feels MUCH better!
