Feebo,
I have used straights and a Rolls for many years. From what you have said I think the Rolls would be just the ticket for you. They are very high quality and have a substantial "hand" feel and provide excellent shaves. As you say that you enjoy the satisfaction of maintaining your razors the Rolls is for you. The cross-section of the Rolls blade is the same as a straight and the Sheffield steel holds a great edge. You can still find good Rolls razors if you keep your eyes peeled. The only caution is to be sure that you don't get one with a broken hone as it will damage your blade.
