If someone is really interested in temp "regulation," the best choice is still probably the Subie unit. They just need to make sure to plumb the cooler into the coolant bypass circuit. That water warms up much quicker than the radiator. Some implementations of the Subie cooler plumb it into the lower radiator hose. I don't think that is going to circulate water until the thermostat opens either.

I didn't intend that to mean the JR dual's sole benefit was warming up the oil. I should have broken it down farther to say the JR setup has better temp regulation then an air to oil, but more thermal capacity then the oe forester unit, which I really don't consider much of a cooler.
Here is a shot of my water temp gauge after 3 hours of freeway driving in 50 degree weather. My oil temp only got to 140F using air to oil cooler. I am pretty sure the JR setup would have given me more "normal" temps, not that I really consider this that much of an issue periodically.
