To me, technique specific setups is all about covering a wide range of water situations and a wide range of different looks to give the bass to determine what they want. By water situations I mean: open water, light vegitation, rip rap, wood( brush piles, docks), heavy vegitation to matted vegitation.
With 3 spinning rods I would keep one medium rigged up with a ned rig(or shakeyhead) 15/20lb braid to 8-10lb fluro. One medium rigged up with mono for finesse crankbaits and jerkbaits. And the MH spinning rod, 12lb fluro with a weightless senko.
With 3 MH-F, i would dedicate one to heavier moving baits with 15lb fluro: spinnerbaits, paddletails and maybe chatterbaits. With the other two I would also use 15lb but have a couple of different looks, maybe one 1/4 t rig and ***/8 t rig. Or vary the plastic on each, one curly tail worm one craw style bait, or one beaver style bait and one craw with more action.
I like to have a rod for pitching heavy wood cover, maybe that's where the super destroyer comes in. Would use 20lb+ Fluro rigged with a heavier jig and t rig. I also like to have a rod dedicated to heavier weeds with braid on it used to rip through the weeds, usually a swim jig with z craw jr or sometimes a chatterbait. I have actually been looking for info on the madbull considering it for a braid chatterbait rod that could also be used for buzzbaits and whopper ploppers. I am not sure if it wouls excel at this or not though.
To me, about the only think your arsenal is missing would be a frog rod for matted vegitation, but maybe one of your MH is heavy enough for this if you put on heavy braid. Maybe also a treble hook rod, a moderate action rod rigged with mono. For my style of fishing i would not need 4 MH-F rods and would look at changing out a couple for a frog rod and crankbait rod, But I also do not fish in Texas let alone Lake Fork so you may be right on the money but would definitely consider at least a frog rod.
