Hi,
haven't fished Eden before but do a bit o f live baiting of the rocks. Normally I run about 3m of 60-100lb trace (depending on what you are chasing) then a float on main line with adjustable stopper (deep adjusted depending on conditions). Haven't really bothered much with bridle rigging bait, normally if using yakka's I just hook them in the shoulder, when using slimeys and frigate a hook in the top jaw will normally do trick. I have also heard when using Frigate you can run no float and simply free spool them out and retrieve them in till they get hit or die, they don't normally last as long as they need lots of water running over gill; yakka's are very hardy and in right conditions will last all day.
When is the best time for LBG at Eden, might have to do a trip down there soon.
