Travis,
If you get snipped on a jig, wind in and tie on a taipan with a rear treble. You will still get snipped on the drop, but not in forward gear, generally with longer jigs and rear hooks the jig itself keeps the teeth away from the line. It's worked for me for the last 30 years!!
Maybe try taking off the assist hook completely and putting a single or treble direct onto a split ring on the rear??
I used wire assists for a while and they don't seem to sit very well, I sorta lost confidence in them.
I wouldn't put wire in front of the jig, generally knocks out most of the strikes.
Try the eastern tip of that big Island up the coast where you catch the GT's in about May or June if you want a big spano...or even the same spot you catch the GT's, so long as its cold and clear
