Have a look at Etoile D'Holland - a beautiful vigorous red with a terrfic scent. It is healthy, semi-double and has some disease resistance. Don't know much about Crimson Cascade but I think the other two do not have much fragrance - and what is a rose without a perfume? In truth, a good scented red climber is fairly hard to find, amid the sea of pinks and whites. Good Luck, suzy
