Purpose of the wacky rig is to force you to be slow and methodical. if you start adding weight you may as well throw a light texas rig.
Partially agree and partially disagree...I don’t think it’s PURPOSE is to slow you down. I think it DOES just so happen to be a slower presentation by default though. I also think that throwing, say, a 1/16oz wacky rig vs a 1/16oz TX Rig is still 2 different presentations. Unless it’s hit on the fall, a Texas rig is designed to be fished along the bottom. Wacky rig is top to middle part of the water column and generally fished with a bait that mimics a dying shad.
Just respectfully disagree that adding a weight to a wacky rig makes gives it the same effect as a TX rig. To me they are two distinctly different but equally effective presentations.
