I have this dilemma. I have two very diferents kind of grass in my ranch, one very hard grass and the other real good grass. You leave the repleasements heifers since born on the hard grass to make the teeth get stronger and then can grass anywere or vice versa first on good grass to let the teeth grow real healty to be ready for the hard grass.

I understand your dilemma, however I am of the opinion that you are stressing the "grass differences" in a manner that is giving too much importance to the physiological influences on the calves bodies (teeth) instead of concentrating on the soil upon which the grass grows, and the nutritional supplements which they may be requiring.
I would suggest that you have the various fields of grass soil tested, and determine if they contain adequate and sufficient Calcium, Magnesium, Phosphorous, Potassium, and Trace Minerals to be capable of sustaining the requirements necessary for proper skeletal development and dental development.
What grass species are your cattle grazing? How recently have you fertilized the pastures with a complete fertilizer, and perhaps applied lime (Calcium Carbonate) to your pastures. to balance the pH of the soil?
It might be a good idea to expand your thinking to go beyond the "Hard grass - Good grass" philosophy and explore other methods of nutritional supplementation - such as a well balanced Mineral Supplementation to augment the differences in grass species you are grazing. Are they getting adequate salt and clean water daily? Also, do the Dams of the calves have sufficient nutrition while they are carrying the calves, and after birth while they are nursing and before weaning?
These are just some possibilities to think about.
