I have a Deep Jungle XL. Never a problem with skeeters, and I enjoy the comfort of the roominess. I'm wonderign why you would want a 4 season in Florida. The climate is a good deal like Texas and 3 season is usually good enough. If it gets down below 30* we just wait till next weekend when its going to be 50*.
FWIW, I think that you will end up wanting an underquilt before you're through. I gave up on the bubble pad that comes wcith the DJ for hiking as its just too bulky. Works OK for car camping, but something as ompressible as down or even synthetic packs easier. AHE makes one especially for Hennessey Hammocks.
If I ever do go out when its going to be around 30* or below, I an just use the bubble pad in conjuntion wth my AHE Potomac and a fleece mummy bag liner inside the hammock with a good top quilt and I an do 20-25*.
