thinking about building a double barrell pvc, not sure how to make the run-up
truth: build-a-jib cult. i built a double barrel PVC rail. i had to buy everything including a driver bit for a drill and it cost $36.00. for the in-run, i set up a roll on type ramp in the dead center of the jump (no gap and you roll straight onto the rail). then on both sides, i have an urban setup where you have a bit of a gap and have to jump onto the rail. its sick in my opinion because my snowboard friends like the roll-on (they are still progressing on rails) and i like the urban setup.
i hope that makes sense
