Terrible idea in my oppinion. Winny really limits your range of motion considering it really dries out your joints, and fst7 envolves stretching the fascia. This is a recipe for disaster and it's not worth hurting yourself. Shoulders will be very septible to injury as will elbows too. Speaking from experience here....you could use a little deca to offset the dry joints but I have never done that personally. Hope this helps!
