i think you've got the right idea by talking to your boater...and taking what seems best for that day. that is what i do..and based on how he fishes and what lake, determines what i bring. i narrow it down to 5, maybe 6 max.
what i usually take...
1) Fenwick Aetos 7ft mh, Citica, 30lb braid. i can use this for jigs, texas rigs, frogs, etc.
2) Pinnacle Perfecta 6' 8" m spinning rod, Pflueger Supreme, 8lb fluoro. shakey head, shallow cranks, wacky, weightless senko, etc.
3) BPS crankin' stick, 7ft mh, BPS proqualifier, 12lb berkley big game, deeper cranks from 8ft to 20ft. maybe spinnerbaits, chatterbaits, etc.
4) Veritas, 7ft mh, Shimano Symetre, 30lb braid, jigs, texas rigs, frogs, etc., buzzbait.
5) Lamiglass 6'6" m spinning rod, Pflueger Supreme, 12lb Tufline Supercast, spinnerbaits, topwater, senkos, crankbaits,
there are prob much better setups for each application...and i'm sure i am "crossing the lines" on how i use some of these but i try to have what is versatile and use what i have to be able to switch and still be as effective as i can be. (obviously, i am not opposed to spinning setups... )
i also have these and will switch out depending on partner and/or lake
BPS extreme 7ft mh spinning rod, Pflueger President, 30lb braid..
Loomis GLX, 6'6" heavy, BPS PQ, 30lb braid
BPS bionic blade spinning rod, 7ft heavy (older rod)
Shimano Compre casting rod, 7ft m (a little to whippy for my taste)
i have those 2 rods as back ups to swap out as needed.
here is an example of a duo-lock i use on occasion..especially for crankbaits.

hope this helps...
it is difficult for us non-baoters to know what to take and then narrow it down, on setups and tackle..
good luck..
