my go to shore fishing rigs are as follows. depending on how i want to fish...
bottom fishing - 1 or 2oz pyramid sinker at the bottom (depending on how the water looks) and a size 2 baithook about 16 inches above the weight to get the bait higher up in the water column. Hook tipped with squid or shrimp until i catch a tiny rock bass then i cut that up and use. (catches just about everything except a flounder ive learned)
cast and retrieve action fishing - 1-2oz chrome kastmasters, or i get these "dragonfly lure" brand lures from Phoenix Fishing in a silver/blue or silve/green color at 1oz and they work very well catching just about anything from shore or kayak (except a flounder)
messing around fishing - usually consists of a white 1oz bucktail jig that i bounce around or quick retrieve just to see what i can catch on it (have only caught rock bass on it)
still yet to catch the elusive flounder. going to spend most of my time during my feb trip trying a smaller chartreuse jig tipped with bait and bounced/dragged very slowly.....
have used similar bottom rig at night and yielded what looked to be some bonefish or the likes and a guitarfish...
