I agree with that 100%. Registered SimmAngus can be no more than 7/8 simm, or 7/8 angus, and no less than 1/8th Simm or 1/8th Angus. Big difference in a 7/8ths Simm and a 7/8ths Angus,. IMO, too much for consistency. And I would not use a 50/50 Simm Angus. Just like I would not use a 50/50 Herf -Angus bull nor a 50/50 Char Angus bull. Dunno why the developers didn't go the route of creating an actual SimmAng breed. A stabil, 5/8 Simm and 3/8 Angus breed, like Brangus, Gert or Braford. That bull I would use. Like you, I'd have no problem with SimmAngus cows, to breed to a registered pure bred bull of a third breed. But even then, I would like for the cows to be the same percentage-wise. Wouldn't want some 3/4 or 7/8 Simm, some 3/4 or 7/8 Angus, and some 50/50, etc., in the same herd. If I were 30 years younger, creating a SimmAngus breed might be an interesting project to develop,
