Dun is right on.
There are good and bad disposition cattle in all breeds, but in general Gelbvieh and Simmental have better dispositions than Angus.
Since your cows have a high percentage of Angus you are also giving up many of the advantages of hybrid vigor.
If your calves are eventually being sold on a grid basis that pays healthy premiums for high grading cattle you may be better of using Balancer (Gelbvieh/Angus), SimAngus, or Braunvieh/Angus hybrid bulls. The resulting progeny will be close to 75% Angus which should give you very good marbling (assuming that the bulls you use are breed average or above for marbling).
If your cattle are sold on a grid that pays better for higher yielding carcasses, you would be better off using purebred Gelbvieh, Simmental, or Braunvieh bulls.
Whether you use the hybrid or purebred bulls listed above, they heifers out of these bulls should make excellent brood cows (assuming that their parents are also of good quality). These females will likely milk better than your high percentage Angus, should wean heavier calves, will stay in the herd longer, and will typically have calmer dispositions.
