"tires" is an inspired suggestion - one often overlooked by those who haven't used a variety of them.
GP4000s seem to be the semi-official tire of the 41. I ride them too. My current favorite for fast rides when the surfaces are likely to be good are Vittoria Diamante Pro Lights. I wouldn't have considered them, but they came stock on my newest bike and they roll like a dream.
