A drop shot rigged with a 1/0 or 2/0 ewg hook and a 3/8oz drop shot weight works really well, but it isn't the only way to effectively fish an area with timber.
I sometimes like to hook up a flipp'n/pitch'n rig and will go up to the timber and bounce off it, around it, sometimes just straight drop it...you never know who might be holding up along the timber. For that setup I like to tie on a 4/0-5/0 ewg hook with a 1/2oz bullet weight that is pegged. I like putting a big tube, craw, or beaver style bait on that.
You also can't go wrong with a weightless worm/stick bait. Just put on a 4/0 ewg hook and work it through the area as you please...you can drag the bottom, hop it around, jerk it through the water, just whatever you feel comfortable with.
In the end, when you are fishing around timber, you are bound to get hung up...it is just some setups/lures will have a more or less likely chance of getting hung up :p
