I agree 100% with OH Breeder here. It is better to breed modestly for a good, live calf experience the first time with your heifer. When she shows you what she can do in getting a calf on the ground, you can analyze her productivity, faults, strengths, and decide how to advance her next mating up to something more high powered or in the range of your ultimate calf goals.
I would not afraid to make your first experience with her by using Angus, Red Angus, Shorthorn, Maine, etc.
I have used Lowlines in the past to give me that extra "comfort zone"-- I highly recommend them to get the first calf experience done and make it much easier. The resulting calf will be a 1/2 blood and most of them are only slightly smaller that their full- size bred counterparts. You may also find that some 4-H families want smaller calves for smaller kids to show...
so you could have a market for them, or show them yourself.
