A little experience with cattle many years ago - but my land is not good cattle country!
The white faces [Hereford] were never a problem - apart from a few calving issues 'cause of big heads!
Tried Angus bulls to dodge that problem - but I would not trust an Angus bull as far as I could kick one! [Mean b.....ds]
Last bulls we had before we quit trying to run cattle were Murray Grey. Derived from Angus  - but wonderful quiet temperament.
Are there Murray Greys in the US?  [or Canada?]
