Sonk, I don't think a light bar would net the same benefit, unless you pointed it up towards the moon. You're looking for aerodynamics, and a light bar is a little too brick-shaped. it would help, but wouldn't erase the wind noise as well as a real fairing.
The one paflytyer made is even better in that capacity than a Yakima or Thule one, in that it completely wraps the front of the rack. so essentially the windshield just got taller- what's probably even sweeter is having the sunroof open on the highway, and still being able to have a conversation, or talk on the (
hands free) phone.
I run a 48" Yakima fairing and it does a pretty decent job, but I'm sure not as well as that one. dude once you get fairing 2.0 perfected let's talk about a consignment deal..
As for small stuff falling through, paflytyer hit it- really not an issue for most of what we plan to carry up there. Camping chairs, camping tables, stove, sleeping bags, duffel bags, hot shower kit, empty water jugs... they span at least 2-3 bars, and then they get strapped down. Even with a mesh floor you'd still strap it down, you wouldn't let anything slide front to back on its own. On a trip last year I clamped a piece of plastic on mine, just to make sure some of the smaller stuff had a floor- not sure if it was necessary but seemed like a good thing to do. Just placed it all up somewhat logically, then used one of those big bungee spider web things around the perimeter.
But worst case if a chair or something actually rotated 90° and fell between the bars, it only has 3" to go until it's on the roof, and then would still kept in place by the side hoops. Beyond camping stuff, most of what I intend to haul is on the big side- 2x4's, plywood, Ikea runs, boats, 10' sections of steel tubing, RTT, Thule box, bike racks... none of which benefits from being on top of a mesh floor, or being elevated on top of a basket area. that's why I went with the low approach.
Here's a "loaded" pic of my own... yeah I know an 80, but hey it's the rack we're talking about. If you look close you can see the winch line... yup I was stuck!
also a 100 series picture with a more "typical" load...
Thanks again for the support guys, feel free to send me emails off the site, or post up to my vendor thread, or send PM's with more specifics. 5cruiser better get over here quick man or I might find another home for this flat one..
