Replying to Rails

So i switched from boarding to skiing this year and of course I bought twin tips because I thought normal skis would get boring. I've only skiied 2 days this season but I've taught myself and I'm starting to experiment in the park. I can slide some boxes and hit some small jumps but I've tried some small low rails and I always eat shit every time. Can you guys give me some advice on rails? Haha I'm tired of all of the kids in the xxxxl jibberish talking shit on me because I wear full tilts and cant slide a rail to save my life.
