My own sets are pretty straightforward. I do not go as far as some might. I do not change sets based on buffs from bards/corsairs etc.

In Abyssea with Apoc/GH/RR

Offhand: Kamome
Ranged: Qirmiz
Head: MKE Head with STR4 WSAcc15 AGI4 WSDamage +2%
Neck: Soil Gorget (I would use a hope torque in place of this, as I know I can stand to use the attack, but I do not own one)
LEar: Brutal
Rear: Centaurus
Body: Loki's Kaftan
Hands: Seiryu's Kote
LRing: Breeze Ring (I would change these rings to more AGI if I cared to pay overpriced amounts for AGI7 rings)
RRing: Breeze Ring
Back: Atheling Mantle
Waist: Anguinus Belt
Legs: Usukane Hizayoroi (I would use Ambusher's Hose here but I haven't bothered going after the horse. It called me fat last time I fought it.)
Feet: Hachiryu Sune-Ate

I could probably stand to make a few changes in that set, but I believe they'd be fairly marginal at the moment so for now that's where I stand inside Abyssea.

Outside of Abyssea the only thing that changes...

LRing: Rajas
Rring: Strigoi Ring

I've considered toying around with a dab of more STR and DEX outside of abyssea. But for now this works for me.
