Well you already have two shots of Dream On so I would find something unrelated to him. I can now recommend Grandmaster. I have had 4 calves by him. All small and lively. The first one did not impress me much at a few days old, but I cannot believe how much he is changing for the better. I love all the heifers by him.
I would be tempted to go with one of the easy cavling, stylish Angus bulls like OCC Legend or OCC Missing Link. They cross good on the Dream On females and come easy.
