Definitely go to the "deep south" anytime the weather will allow. The scenery is spectacular and there are endless wading flats.
There is hardly any grass at all down there. The current rips through the maze of cays on tide changes which might explain it.
The creeks are awesome and a great backup plan if it is too rough.
By the end of the week I had pretty much settled on a #4 gotcha with a long wing of "shrimp" craft fur for just about everything.
There are sharks and big cudas everywhere so be prepared. At one point I had a hooked bonefish being chased by a 5 foot cuda being chased by an 80# lemon shark - all right in front of me! The cuda won out on that deal but I got a few good jumps out of him
