RE: Reflex set Up or Down?
Not knowing any other details of flying, I would say you might have some positive incidence on your wing or some slight positive on your sta.
Moving both ailerons slighly down have the same effect as adding negative to the wing. Try the ailerons and see if that will fix.
Also try slowing down by making your final longer or turning tighter to final therby losing speed.
Good luck
