Replying to Help with Rails

So after skiing for 17 years and being a backcountry skier and a big mountain skier I've decided the park is the next place I should go (I know it seems kind of insane that I wouldn't have done it sooner). I've gotten pretty good with sliding boxes and stuff but now want to get into rails. What advice have you guys got for skiing rails, obviously being sendy is key to everything, but beyond that what are the big points for hitting rails?

Appreciate the advice!
