For a Blue Roan color pattern consider a Speckle Park: Check them out at: http://www.codiakacres.com/bulls.htm. Note these cattle have Shorthorn and Angus in them hence the color pattern.
We've used about 40 units of blue blood and have had some very good calves. Good consistency and sounder than most clubbly types. Placed one last year at Fort Worth. Our Best heifer this past year was a Blue Blood X OCC Jetstream.
