Hey SCott,
We do a fair amount of Live baiting for GT's here in South Africa, with good numbers of 50 kilo plus fish being taken off our beaches every summer, especially on our North East coast and up into Mozambique...
Our conditions dictate the use of long 12' to 14' surf rods, coupled with large overheads like Trinidad 40/ Saltiga 50 reels or similar, usually spooled with about 200 metres of .55mm Mono over a 600 metre braid ( usually 50lb ) backing...
These guys use one of two methods:
Non Return Slide Trace:
This involves casting a 8oz to 10oz Grappling sinker as far as you can ( these guys push it to 120 to 150 metres ) and getting the Grapple sinker to "sit" solidly in the sand/reef...
They then clip either a deadbait or live bait onto the mainline, by use of a non return slide trace which they then slide down the mainline by bouncing/swinging the rod.... its an amazing system which allows one to send a 2 to 3 kilo bait a good hundred metres out..If you google Non Return Slide Trace you should come up with some examples and a better description than I have given here...
The other option would be Swimbait Trace:
This involves swimming a large live bait directly off the beach... The shark boys here in SA use anything up to 70 kilo rays/Skates to fish for Bull Sharks and Tiger SHarks off the beach... but the guys focusiing on GT's usually use a small Tailor, a Wave Garrick ( Spotted Pompano ) or best bait being a live bonefish...
These baits are hooked and swum directly into the surf... and basically allowed to swim till they get eaten...
Most concious anglers are using a single circlle hook rig for this...
Obviuously tactics off a boat are completely different, but should be pretty simple... live bait with a bridled circle and you're in business... small Bonnies or similar are like GT Candy and will get sucked up!
Granted we would all prefer to catch GT's on Jigs and Poppers, but sometimes the fish will only eat a live bait, and I for one, after 3 days of popping or Jigging with no love, and I know the fish are their, will not turn my nose up at swimming a Livebait on my popping rod for a bit of fun....
I think that admitting to that on this forum is akin to commercial suicide, but I'm a fisherman, not a purist!!!!!
And standing on a desrted beach at sunset wityh a live bait kicking out through the surf while you sip a beer is a pretty fine way to enjoy the end of a good fishing day!
