The rig I use is a set of 3 or 4 x VMC 4/0's connected together with swivels, then a swivel, wire trace, swivel, sinker, swivel, main line. I find the swivels make it a lot easier and quicker to put on the bait. Have also found that some brands of hooks when ganged together can come out unless you close the eye right up, but this makes it difficult to gang the pilchard.
A quick scan of one of the 3 hook rigs
Some just use a single hook and a chunk bait though, personal preference i suppose.
