The thorns vary from one variety to the next, but it does seem many DAs have thorns like old roses. Some have more of an old rose growth habit, arching with long canes, which can be more troublesome than an upright grower- they seem to reach out and snag me with those thorns sometimes. Time to establish varies from one variety to another as well. Most I've tried have been susceptible to blackspot, which I'm thinking could be an issue in your area, but there again, that varies from one variety to the next. Are there specific varieties that you're considering?
You may want to check into Meilland's Romantica roses, they have old rose style blooms, but generally aren't as winter hardy as Austins. They may be better suited to warmer climates.
