ok heres my fix for the BIG AIR i use a fold up table small and square about 3ft wide i pull out 2 of the legs set the table where i want to jump (or what i want to jump) the to soften the sudden change in slope i use a cardboard box folded flat and lay it with the center of the box on the base of the slope i can do a double easy and get somewhere around 6-10 ft. of air its a sight to see try for yourself if uve got the balls the longer the table the less the air but the more control due to the less sudon slope change
