I have looked into Gelbviehs and Balancers myself. It seems they recommend the full-blood Gelbviehs to be crossed with your predominantly British herd to get the 50:50 cross in order to obtain optimal hybrid vigor. Once you retain the offspring, then they say to use the appropriate Balancer to maintain the desired percentages. This also may just be marketing jargon.
I just couldn't find a Gelbvieh breeder in close proximity so we are looking at Limousin for a terminal cross with our Brangus. I also can't get myself to believe a Balancer on Balancer will give the same hybrid vigor as a Continental on British cross as promoted by their material.
For sires I like Simmental but their frame was an issue. I like Limousin but their low milk production was an issue. Those two factors led me to look into Gelbvieh as a possibility.
