Lately after wheeling during the winter, driving a bunch of buggies, and having my own chopped XJ, I've come to a conclusion.
Even when I build a full-out buggy, I will *always* have a roof and a windshield of some sort. It took just one time of getting caught in the rain, or going fast on a dusty day, or sitting out in the sun all day long, and that decision became really easy.
I'm very happy with the level of chop & cage on my XJ right now:
I had it out over the weekend and just about every inch of the exo bars got scratched up, but the windshield and A-pillars stayed fine, and the rear quarters didn't get beat up much at all.
