G'day Flashing,
Aside from his obvious extraordinary race track ability, as an aspiring sire the single biggest thing Rock N Roll Heaven has in his favour is that his bloodlines allow him to cover virtually ALL of the best producing broodmare blood currently available here in Australia.
Artsplace, In The Pocket, Mach Three, Cam's Card Shark, Cam Fella, Jate Lobell, Albatross, Falcon Seelster & Classic Garry line mares that you can send him...you name it, he can pretty much hit 'em all. I even think he's far enough down the line to take a reasonable shot with mares by Badlands Hanover, Rustler Hanover, Red River Hanover and so on.
I just went through the list of the Top 20 2yo, 3yo and All Age Broodmare Sires of the past couple of seasons here in Australia and IMO there's not a single one who's mares he could not reasonably be bred to. A lot of people probably don't fully appreciate just what sort of an advantage that is to any sire setting out to make a name for himself.
Good luck with your horse Mr. Bellino. I'm looking forward to seeing him. Those back to back 49's that he paced to win The Jug were just incredible. That he kept on pacing such miles in so many races after that point was testimony to his heart & soundness. A great colt, no question.
