yea pvc slides fine...get a 10ft long pipe of pvc and cut slits in the bottom where you want the kinks to be so you can bend it into the shape of your rail...
Oh, and I was thinking more along the lines of plexi board. I don't want a pipe. I want a strip that I can glue down with adhesive like liquid nails. Or get thick enough plexi that I can get some beveled drill holes into. It would be awsome If I could buy a strip of steel with pre-drilled beveled holes. I'm sure it's out there somewhere, but how expensive is the real question.
Alright, why don't you guys build me a rail if you're so worried about how short it is. Thanks for volunteering. It's my first rail ever and it's just for practice. I'm not trying to make the next hit ski movie. But thanks for the input.
