I've pretty much have taken off all my treble hooks on the jax jigs also and have added butterfly stinger hooks to those as well as my heavy Megabaits, heavy diamond jigs, Yozuri's, etc.
I would place all stinger assist style hooks to the top ring. From my experience you don't have to work Jax jigs much...once you hit bottom crank up a few times and wait for a bite...maybe try a slow lift and drop and follow the line down if you get bored, or try winding to different depths since different species sometimes congregate at different depths.
