I have some Russell and I wish it was Tift 85. They don't graze it as readily and it bleaches fast when curing. No trouble establishing the Russell though. Russell will outproduce Coastal by about 10% but the cows don't seem to like it as much.
Going to stick with Tift 85 in the future, primarily for grazing because it's harder to cure than Coastal or Russell hay. Will keep baling my Coastal and Russell.
