Apart from the titanium Starry Varius, which I really liked, I haven't seen other DB models for real, unfortunately.
I think I would like the DBs you show me very much as the DB15 has these wonderful ogival lugs and the DB25 is very close in many ways to the Starry Varius.
On photos, I don't respond to the more "futuristic" pieces, but of course I might react differently in real life.
Best, Emmanuel
