I guess I am biased due to I use more than anything else but, personally I think you should try the carolina rig. If your just fishing bottom and no specific structure, it is probably the best search bait you can use as a beginner. For a start I would try a 1/2 barrel weight, red bead, brass bead, swivel, a 3 to 5 foot long leader, and a standard 3/0 worm hook in that order. You put the weight first, then the beads, then tie the swivel to your main line, and then tie your leader to the main line.
Just remember sweeping is probably the easiest and best way to set the hook. Setting the hook upwards, with the swinging weight, may cause it to come loose. This is probably why some consider the T-rig better cause you really do not have to worry about the hook set.
Also remember it is not just a deep water technique. You can through from 20 feet of water to a foot of water I promise you it does not make a difference.
Good Luck,
Austin
