You need the Carradice Barley in Black with white strapping. I bought some of the Minnehana bags from the Restoration Hardware clearance...and...they are fine for the money, but they really can't compare to the Carradice bags!
Best deal I've found on the Carradice is from Wiggle. I bought the Barley, the Bagman support, and a Wiggle water bottle for $78 and got free shipping.
I run the Barley on my Super Course and really like it...it's just the right size for daily use as long as you don't need to carry more than an extra shirt/windbreaker/etc. along with your tools/tube/tire.
