It will just be closed more often in the winter than the summer. That being said, i would go w/ the larger unit.

A thermostatic plate doesn't block all of the flow to the cooler. Say you are running a 180* thermostat, at temperatures below 180 degrees it is only about 90% closed.

This is going to make it very difficult for the oil temps to get to where you need them in the winter, so you want to block part of the cooler to reduce it's cooling ability and help get your temps up in cold weather.
