You should not have an issue with wind noise at all. They are down low on the Pillars so wind noise isn't really an issue. You get wind noise with roof mounted light bars though.
As for Rigid or Baja. That's up to you. Now, I'm a big Baja fan. We're one of the largest stocking Baja dealers around so we really love our Baja Designs lights. That's not to say Rigid makes a crappy product. By no means is that true. They make a fine product as well and their new 360 lights should be pretty cool. I'm not a fan of the whole back lighting thing to be honest. I always thought it was more of a gimic to get folks to buy lights... and as you learned, it worked like a charm
Pretty back light but not a lot of light. With that said, the new 360 doesn't give you a back light with pour light output. It actually gives you some decent light output. So that's a benefit. And the new Radiance Scene lights give you decent output (it was always a complaint from Radiance owners... they loved the back light, hated the output, thus the scenes came out to solve that issue).
So should you do Baja or Rigid... well my money is on Baja... because it's a ROCK SOLID light and you can change the lenses later if you want. I don't think you need a large light up there though like an LP6 or LP9. The 360 is a big larger for my money because of that round shape. I run XL80's on my own demo truck and even that size bugs me a little. See I like things nice and sleek. BUT they sure work great.
I ended up doing spot lenses on my XL80s (not sold that way but you can throw the lenses on without an issue). I have no issues with glare either (blue truck) and they work amazing. In fact... the XL80s put out so much light when I put my 4x LP9 Pros on, you can still see the XL80 down range (nice spot pattern is why, i use driving/combo LP9s)
Whichever road you end up taking I can hook you up with some nice pricing. Just shoot me a message.
To be honest... as much as I love Baja i'd say get the 360 so that they match the rest of your truck. Tie them into the same control wire as your fogs so all the back lights come on together.
