Radiant barrier on rafters or directly on deck?

I'm going to be installing a radiant barrier this weekend, Location lower Central Florida so my only goal is keeping the heat out.
From everything I've read radiant barriers need an air pocket to be effective, but the manufacturer of the radiant barrier suggest you can staple it directly to the deck if in a southern climate. I assume they suggest that method in the south to keep heat out.
Page 3 here http://pdf.lowes.com/productdocument...hRQXZEX0J3RQ.. advises a direct to deck staple method.

Should I hang it between the rafters creating an air channel, or should i staple directly to the deck?
