What is everybody's favorite wash/rinse temperature setting?

My darks I wash in cold/cold, but once in a whle if they are stained or real dirty warm/cold and a bit extra soap.

Lights warm/warm

Whites hot/cold with bleach.

Cold for all cycles. Here in Florida, near the Gulf of Mexico, in the summer, the cold water is warm; because they cannot put the water pipes too deep in the ground because they would hit water. We are at sea level.

That's what I use most of the time, but sometimes I use cold wash and rinse for darks and delicates.
