Muddy man,
Here's my $0.02 for what it's worth. Just like the others posted, this is very subjective and rules are very general.
Soft plastics
This includes senkos, T-riged worms, Spot Removers, tubes etc. I have three rods I use
1. 7' MBR 844C IMX - MH (Loomis calls it heavy) my main plastics rod.
2. 5'6" Lamiglas XC 66 MH fast - I use this for pitching under overhanging trees & bushes.
3. Loomis SJ722S IMX 6' Med. Fast (spinning rod) for skipping under docks bushes etc.
Jigs
I use three rods for Jigs with trailers in different conditions.
1. 7'6" Loomis FS904 IMX 'flippin stick' for pitching jigs (and 12" worms) in heavy cover (my favorite fishing) and I will sometimes cast frogs with this rod.
2. The same 5'6" lamiglas above for pitching and skipping Jigs in close quarters.
3. 6' Loomis CR724C IMX heavy fast for swimming Jigs in rocks, ledges, open water, etc.
I don't fish c-rigs or live bait for bass enough to help with those. Now catfish and saltwater is another deal and a long post.
Crankbaits & spinnerbaits
I am learning to fish crankbaits even now, as I have always hated fishing them, but based on what I have learned here, I built myself a 7' MH Lamiglas BMB841 all glass crankin stick. I have always liked to feel the blades turning on a spinnerbait so I will use this rod for that also. JUST FOR YOU MUDDY - The 7' Lamiglas rod I built for you is very similar to this one, that's why it seems so much bigger and less stiff than other rods you might compare it to, fiberglass is not as compact as graphite, but is very strong. You have an exceptional deep crankin stick IMO.
Top water,
Loomis CR 722C GLX 6' Med. Fast for LC Sammys, Spooks & Rapala floaters.
Loomis CR 724C IMX 6' MH for Buzzbaits, Jitterbugs, surface poppers.
Finesse Fishing & dropshotting
Loomis DSR820S GLX Light extra fast spinning rod. this includes 4" senkos, finesse worms, mini tubes, etc.
Too many freakin rods (and reels) to keep up with, but it makes me think I'm doing my very best to catch fish. I hope this helps you my friend.
