Michael, the EBs call for trolling unless you want to be cranking up from 600+ feet. It is the edge of the continental shelf and is an area where there is a very steep drop off to mucho deep water.
I am not sure about rigs in the area. I don't fish down there anymore so I don't keep up with the comings and goings of the rigs. If you are signed up on Tom Hilton's site, you can get up to date data on the rigs.
That part of the Gulf has produced many billfish and my first YFT came from there. Good luck with it.
