Ok..... I know the spot your fishing and if you fish there often you have probably stood next to me. depending on the tides (I usually fish slack to slack on an outgoing tide )you need to vary the weights you use a TON!!!!. slack you can use that 1oz. and hold the botom or none at all but when that tide starts going out 1oz is doing you nooooo good. you need to feel that rig bouncing the botom or your just picking up (random /luck )fish.
I use 5 oz when it's cranking and taper down as the flow drops
4/3/2/ also try bouncing a jig in the same manner. But if you are only using bait I would use clams/worms they seem to outfish the chunks there by a longshot for me (If you can catch some macs use them live). you will get the feel for the right drifts when you start to notice your bait bouncing the botom( keep a fairly tight line w/ no slack so u can feel the botom and a take!!!) 10-o'clock to 2-0' clock drift..and haul it in lob agan. good luck...
