John, I ran this exact setup on our 2018 Raptor before we installed our ADD bumper.
We had the Unlimited Fog Pocket Kit and the 30" S8 behind the grille. We went with the standard Driving/Combo pattern that was offered.
The S8 got its name because it has 8 individual LEDs in each 10" section of the bar. When you choose the Driving/Combo pattern, you're getting 6 spot LEDs and 2 wide cornering LEDs per each 10" section. So 75% of the bar will be spot pattern with only a touch of it being wide.
Honestly, the amount of coverage vs distance was perfect. Due to the mounting height of the bar, the S8 projected further than our Unlimited Fog Pocket kit and was a great filler for those highway speeds.
We got our S8 back in 2017 before Baja Designs started utilizing the newer technology that nearly doubled the output of the previous bar. In my opinion, it's the perfect setup to go with the Unlimited Kit.
Here's a picture of our truck when it was at this stage:
Please let me know if you have any other questions about the setup. I'd be happy to discuss them with you.
