Well Fred's got my Graham Thomas because it really is a superb rose but as well as that I would go for hybrid musk and I think of all the hybrid musk, my favourite is Felicia because of that silvery pink, lovely double shaped flower and that is very very heavily scented and I would have to have  the bourbon rose the th the double white creamy white bourbon rose, if, you could almost eat that, that won't get more than about six foot and you can prune it to keep it in shape a bit if it begins to get too straggly.
