I had 4 KCs on a roof light bar. I got a lot of glare off the hood, but I also have a white jeep. If you do windshield lights, you can tilt them out to the side, which is what my father does on his and he doesn't get much glare off the hood.
I'm not familiar with the lights you suggested, but I do recommend KC daylighters, or if you plan on doing a lot of light I would recommend looking into HID lights. with 6 130w lights, head lights, and fogs, at idle, my volt meter would drop to almost 12v. lots of lights need lots of power!!!
