im planning out my summer jib set and i dont really want to spend a lot of money on it so i was planning on making my down ramp out of pvc putting them horizontal to the ramp and at 0.5 ft intervals. i have a 19 ft ill in my back yard but it only drops 2 1/2 feet so im planning on building a 3 foot base at the top of the hill to make a 5 1/2 foot starting height. has anyone ever tried this or have any ideas to improve this before i start building? im really wondering if ill have enough speed to be able to get all teh way through a 10-15 ft rail... any thoughts are great, thanks!
