My biggest drop is only about 5 foot, but I am going to try around a 7-8 foot in the next week (new one just built near me). My biggest drop gap is only the stairs at southbanks skatepark, so not huge but I need to find something a bit bigger. I am thinking of trying a drop gap about 5foot drop with 4 foot gap onto a rail, then drop into the road, but I have to wait until it is bone dry and there are no cars around! I'll still probably kill myself.
