I have a set of Eric's winter guards too. Case500D does too, and I think he has a pic of them in a post somewhere. He actually made the 1st gen templates for Eric. I like 'em, and the price was right. I had been running around with all four on, but a while back I removed the fan to experiment. Now I'm running the top two only. This allows enough air flow to keep it cool unless I'm towing.
