Ashton,
Here is my opinion on the question, I have some experience since we do it both ways (Hereford cows x Angus bull and Angus cows x Hereford bull).
Hereford Cows x Angus Bull
Pros
1. Hereford cows will be cheaper,
2. Easier to deal with if you tag at birth
3 Better selection of Angus Bulls
Cons
1 Pinkeye / cancer eye.
2. calves will be probably be lighter at weaning
3. udders on Hereford cows not as good usually
Angus Cows x Hereford Bull
Pros
1. stouter calves at weaning
2. quality cows are easier to find
3. no cancer eye and less pinkeye problems
4. better udders on the black cows (generally)
cons
1. more protective mothers at birth (can be a problem if you tag and weigh calves at birth)
2. good hereford bulls are hard to find, cheaply
Personal opinion, you should buy some Baldie females and cross them with a terminal Angus bull, feed the calves out and really ring the bell on the carcass end of the deal. The true advantage of the baldie is the female, the steer calves gain pretty well but the 3/4 Angus hangs a better carcass and at the end of the day isnt that what we are producing..
