It's my second year into snowboarding spent mostly all my time free ride and this year I wanted to learn some park basicsYou don't really have to on reverse camber or hybrid anymore. Mostly camber.
But if you want to you can on the tip and tail to 1" past contact point.
For park, if you have do boxes and rail you can detune the sides, but if you are hardcore then you should know this already.
basically, just go and ride.
