Big bass the term wacky rigging referres to fishing with a bait like a senko with the hook in the middle of the bait rather than in the end. Fish it weightless and rig it like Joshkeller said to eleiminate having to put a new one on every fish or two. The senkos are expensive and you will go through a ton of them if you don't use an o ring. Smallys love this type of presentation because it kind of floats down gradually and looks more realistic to the bass.
