I have the Drake hold downs and LOVE them. However, they are a bit expensive. The cables have never once touched the paint or moved the slightest at highway speeds. Pics below. I think some people have taken some videos of them at highway speeds that also confirm this. You may want to do a search if you are interested.
Thanks, that's good to know. I really like the design
I don’t have the Drake hold downs but I can tell you that the cables will not hit your Jeep. That was one of my concerns too and since I’m close to Drakes I was invited to take a look of them mounted on one of their Jeeps. There is absolutely no way the cables will hit.
Read here that the the stock JK front-end is raked down and the aero-dynamics pushes the hood down. If you lift it and get rid of the rake you lose the wind-force pushing the hood down. Mine's a 2010 and can't say I've noticed the issue, maybe they fixed it on mine.
Out of curiosity, why do Jeeps use the two latches to secure the hood?

I had two (on the passenger side, both times) hold downs actually break on my TJ passing semi trucks on a two lane highway about 6 months apart. First time, thought it was a fluke, second time I went to war with Chrysler. They said they had never heard of them breaking. There is no recall and all Jeep will do if it happens is replace them. They refuse to put any locking ones on them, saying they weren't OEM. Let me tell you, at 70 mph when it snapped my hood buckled about 12-18 inches on the passenger side, scare the bejesus out of me and my passenger. Because Chrysler wouldn't do anything I bought the Hood Locks. First thing I did when I got my JK was put on Daystar Hood Wranglers, no flutter whatsoever.
The Wranglers were originally designed to have the front lower than the back to improve fuel economy. Most lifts don't take this into account, so once it is sitting level the aerodynamics are off and the wind gets up underneath the hood.
So my recommendation is to use the hood flutter as a good excuse to put a winch on the front bumper to lower the front end slightly.
