9's or 10's probably though they are going to looked seriously hucked off a jump that small. What kind of jump is it? Cheese wedge style step down is going to give you a little more margin than a step up or table. 35 ft is plenty big for a progression feature. My preferred method is to dial things in the smallest feature I think it's possible to do something then slowly step it up. If you use that approach, you can definitely get 7's and 9's down on a jump that size.
