Basically I am building a Quarter pipe to put in my back yard i was thinking of just building a 4' by 8' ramp as the instructions say but it appears that it may not be to fun on a bmx so i was hopping there was sum1 out there that could give me a pointer as to which size would be good im only looking to go taller not wider.
to add to this im not looking to go to complete vert but close is alright.
