it's similar to what i use - weight on the bottom, hooks tied on droppers up the line, so you get that weight stuck in the sand and the bait fluttering around above the bottom.
not too hard to set up. i usually carry a couple dropper setups in a leader wallet along with a bunch of pretied hooks. for the dropper i tie on a snap swivel, then two dropper loops about a foot apart. for the leaders i use heavy line(like 12-15lb maxima) and a small hook(i like a #2 or #4 octopus), just about 8" long and tie a loop on the end. the short stiff leaders don't tangle as easy as they do with limp line, and the fish don't care.
i rarely ever have to tie a new dropper setup on(unless i get a backlash and snap off my gear mid-cast), so that's the reasoning for the spares. if i wreck a leader(as is often the case when de-hooking fish with pliers), i just un-loop it from the dropper and put a new one on. not having to tie knots is a big consideration when getting pounded by surf, your hands get cold and it sucks to miss out on action in the middle of a hot bite!
most times i'll bait one hook with a piece of shrimp(uncooked prawns make great bait, they hold up really well and the perch like em), and the other with a 1" rubber grub. usually you get bit on the bait, but if miss the bite and lose your bait, you still have a chance of getting bit again. not to mention you can get a double if a school is passing by.
