Ridge vent for wind

Looking for high-wind approved ridge vent to replace the metal "cap" type that sticks up above the shingles that's on my roof currently when I reroof it. I'm seeing these plastic things that go under the ridge shingles. Is this what I want?

As usual in Florida I'm seeing cautions to use only "high-wind" components but am not finding them even in the local stores. How do I tell if something is acceptable for hurricane winds? Vent seems like a vulnerable spot and if the vent goes you've got a long hole in the roof.

All I've ever used is Shingle Vent II and never had any water get in.
Highest wind so far was about 114 MPH during Isabel.
I'm right on the water and it's not uncommon to get 50 MPH winds here.

That looks pretty cool but I downloaded the PDF instructions http:// http://www.google.com/url?sa...65058239,d.b2I and see nothing about Miami - Dade (or any) aporovals.

BTW, how long a roofing nail do you need to nail the ridge shingles over this thing? It looks about 1.25" thick. I've never seen a 2" roofing nail.
