Not sure about Top Gun, but if you are looking for a red bull to add depth, Amigo all the way! We have had two calves by him, and both got exceptional depth (where there dam's were lacking in depth). He will not power them up, but he will not take it away either. The only thing I do not like is his milk EPD, but if the cow is OK, you should be fine. Simmi's don't typically have a problem with milk production!!!
