In the morning, we just get the heavy water out of them and get them into the cooler as soon as possible. There are fans in there, and they take care of the rest.
At night, its a completely different story.
We will have at least 2 fans behind a steer, brush for about 15 minutes (2 or 3 people on 1 steer), then blow them out until they are probably 75%-80% dry. Then they get the sheen and roto brush. Then blown out again. Then they get the oil, and blown completely dry.
I am personally not a huge fan of a blower, other than lower leg hair and getting the majority of the water out of them. As far as hair training and quality...I really prefer fans and brushing. The fans blow it forward, and we brush it up. The hair will really lift. We take butt fans with us to shows just for this reason. We put a fan behind them in that blocking chute when we are fitting. I just don't know of anything that I like better.
