I have my own practice track with a few jumps but i want some more. The guy who built part of my track for me did not finish the 60 foot triple so i'll have to do it myself, and i was wondering how big and at what degree i should have my takeoff jump be. i want it to be a mx style jump and not a sx style. it will have about a 120 foot run at it coming out of a 90 degree corner. thanks for any help.:D
