I have some in the oven, so I haven't seen any first hand out of my cows, but many have told me Rendition is supposed to clean up pretty well. He has had some pretty stylish calves. Dream Catcher is also one I would look at.
A.I. Guy- Most that I have talked to say that Explorer makes fronts sloppy. I am glad to hear that that isn't entirely true! He does keep rib pretty well and gives them a nice look though. Just depends on the cow!
Grandmaster has cleaned up fronts from what I can tell on my cattle, but I have seen some with plenty of leather at a few sales.
Dream On is also a choice, but he is everywhere.
