I rather like Keiths' screen idea. And I've yet to hear from the guys w/huge winches blocking almost the whole rad area complaining. Blocking 60% of the rad face? I stow my winch for front or rear use, and have a screen inside the grill. My stock HD cooling system keeps my hi-po 360 cool. Not to start a war, but less cooling is better than no cooling when a rock takes out your rad. Add extra fans, lower t-stat....but a screen has saved my butt a few times.
I've also learned that sometimes... when people don't agree with you .... its best to hold them down and kidney punch them till they agree with you
