I'll go into more detail for you =)
Move around.... A lot! If you fish a piling for more than a few minutes you're waisting time. Usually if there are fish on the piling they'll find your crab in the first 30 seconds.
When your bait stops falling lift it back up a few feet before letting it settle on the bottom. I found that a lot of heads will actually catch your crab on the drop. If you lift up before letting the bait settle it makes sure your bait is on the bottom and not in a heads mouth.
Use braided line, and a flourocarbon leader, small hooks, and enough weight to keep you on the bottom with a tight line... I use 3/4 oz.
I prefer a 6' rod with a 1000 size reel to make it easier to get in tight with the pylons.
When you feel the fart start reeling slowly and if it feels heavy give him a bass masters hookset.
i agree with this but i woukeint go with the bass master hook set it should be a gradual pull not a jerk. Also we cut rods down to 5 foot

Just because everybody likes pictures =) You can also see what I use for weight
