If you are on the road they will be slow no doubt.
That is why I am getting Speed Kings.
I used to run WTB Vulpines (but they don't make them anymore).
I am not sure what is available in 650Bs but I am totally hooked on semi slicks. I did a tour in Brittany on tarmac and gravel with Scooter and Fox on Challenge Gravel Grinder plus 38c. They are perfect for the type of cycling you are talking about. For heavy duty touring the Speed Kings will offer same low rolling resistance with side knobs for confident cornering but more volume.
EDIT: Furious Fred might be worth looking at as well.
