I picked up a couple of Kordes roses from the "Parfuma" series 'First Crush' and 'Summer Romance'. Both are deliciously fragrant and showing excellent disease resistance, but are both pinks, one soft blush, the other medium pink.
I think its a matter of finding varieties that will get large enough to have flushes of loads of blooms- that's when you'll really detect the scent from several feet away. When my Leontine Gervais was huge and in full bloom, that light, sweet scent was detectable all around the front yard- it was wonderful! And smelling an individual bloom, I wouldn't describe the scent as strong, but it is pronounced in mass.
Bourbons tend to have a pronounced fragrance, although many are one time bloomers. I have one called Banshee that I typically smell before I see it blooming- as soon as the buds start to open (even just one), I detect the scent from several feet away.
