Well. With the 80 Cap approaching and my gear upgrades reaching a stalemate; I guess now is a good time to post some of my sets.
Cure V Gear:

42% Cure Potency. I used to carry a Holy Ampulla; but due to space issues I don't carry it anymore. Obviously start to cast in Cure Clogs.
Cure II-IV and Curagas:

Heavily focused on -Enmity. The massive Cure potency has made me use Cure III-IV much more often than Cure V, which is now a waste of MP most of the time. This set has an option of adding a Staff Strap and a Theta sash for more heavy HNMing.
Neutral day, no Med ring Cures:
Barspells:

Barspells do 127 Elemental resistance. It is set to macro in my MDT pieces (Kebbie, Coral Rings) when I have them on my Inventory. The briault was a gift from a friend :3
MND Gear for Paralyze/Slow:

This set has suffered a bit from Inventory issues. I no longer carry my Healer's Cap +1, my holy Ampulla, my MND+1 Earring; and only occasionally carry around my Kirin's Pole for more MND (No Shield for me). In its glory days I could get 167 total MND with food and pole, with still room for improvement.
Enfeebling Skill (Silence/Sleep).

Not much room for improvement here. Altruistic cape and an Enfeebling earring are the only two upgrades I'd consider, but the set is already vastly overkill for anything that doesn't need ES. I don't think I could carry the Enfeebling Earring around either (Cassandra/Helenus not even worth considering).
Dark Magic (Aspir and Drain).

Body Has M.Accu and MAB (For my SCH). This set still has a bunch of obvious upgrades to do. First one would be Nash Mantle (Long story why I don't have one) which could allow me to leave the Redingote home. Second would be Dark/Helenus Earrings. There are some minor M.Accu pieces that I could carry around, but don't feel like they justify their space (Sturm Report, Goliard Hands, Witch Sash for non-dark weather, Dark Grip).
My modest Repose set:

Still needs Marduk Head (No money ._.) and Altruistic Cape. However, I'm not sure if I actually want to swap in Marduk head for this one; as I really like the Haste on recasts (Why it has Goliard Body and Blessed Feet). Repose is extremely accurate to begin with; and I think I have been resisted only once on a neutral mob since the day it was added. And I guess the 10% Interrupt doesn't hurt either....
General Purpose Haste Gear:

I use this to cast haste (11 Seconds recast with it and Light Arts), Raises, and -NA's. I've considering adding the cheap Haste+3 belt to cap it, if I can ever make more Inventory Room.
Max MP:

Can still go higher, but this is where it usually stops on the gear I regularly carry around. Ethereal Ring and Dryad Staff are of the first things I leave home when I need space, tho.
My Iddle:

This set has also suffered a bit. It used to carry a Flawless Ribbon; but after losing my Goliard Trews for Dragon Pants, and with Esuna needing the status to actually land on me, I decided to opt for more MP. 914MP was lower than my Comfort zone for an iddle set (And had more than 300MP Difference than my MaxMP).
The most important upgrade I could do is to get some HeraldsGaters, then respec my Dragon Pants for Cure Pot/Enmity, and iddle in Heralds/Goliard. Also, I could get a Colossus Earring, and HQ my Cape.
I have a command that adds more PDT (Jelly, Goliard); and one that adds more MDT (Kebbie, Coral Rings) if I have them on me.
Finally, my resting set:

Not much to see here. I think this one has reached a nice status-quo, where I am unwilling to add more minuscule hMP upgrades because I don't have the inventory for it (I can barely justify lugging the Invigorating/Ariesan already). The only two things I might consider are the Augmented hMP+2 cape (yet to see it), and a Star Ring. Also, I could probably get a Gnole torque and leave my Ajari/Beak home, but this would hurt two sets to benefit one. The Inventory space is very very tempting, tho.
I still have more sets. Like my makeshift Devo/Subli set, my WHM Nuking set (It's actually pretty nice, Novio an all <.<), Stoneskin, a Healing Magic set for Doom (Just in case it actually does something), and tons of random melee setups.
I've been very careful on my choices: but if anyone has any suggestion, or finds any flaw on my reasoning that could improve my sets, please say so.
