Ultima Choker of Aiming BiS question.

Hey guys, I'm trying to get a good gear set to revolve around my (hopefully coming soon) Elfin Bow. You can check out my gear on lodestone, but to save you the trouble:

Main: Relic Bow
Head: DL
Body: Myth / Necklace: Allagan
Hands: Myth / Earrings: Allagan
Waist: DL / Bracelet: Allagan
Legs: Myth / Ring1: Gryph HQ (Quad Meld with +12Crit/+8Determination, no VIT yet)
Feet: Allagan / Ring2: Myth

This totals me to 445 Accuracy, 455 with Food (HQ Deviled). I know that's pretty low, but in all the Twintania fights I've accumulated, my hit% never dips below 99%. I truly believe the accuracy cap for BRD is much more lenient due to Hawk's Eye, but that's a different topic.

When I get Elfin Bow, my Accuracy will crash hard, so my new upgrades will be...

Main: Elfin Bow
Head: DL
Body: Myth / Necklace: Ultima Choker of Aiming
Hands: Myth / Earrings: Myth
Waist: DL / Bracelet: Myth
Legs: Myth / Ring1: Gryph HQ (Quad Meld with +12Crit/+8Determination, no VIT yet)
Feet: Allagan / Ring2: Myth

The above gear set will give me 449 accuracy, 459 with food. Replacing the belt with Myth will dip it down to 440 without food, but getting the Bard's Chapeau or Allagan will bring it up to 444/450.

SO! My question is: after upgrading my gear, I'll be losing +8Determination/+2DEX from accessories and +33accuracy/+23Skill Speed from Artemis Bow, but gaining +4DEX/1WDMG/+34Crit/+18Determination from the Bow. My endgame accuracy will be 454/459 (depending if I get Allagan Visor anytime soon) with food. Is the trade-off with the accessories worth swapping into Elfin, or is there any other thing I can do (crafted accessories, ie) that'll beat this set-up? Allagan Trousers of Aiming is not an option, as my coil static is still working on beating Turn 5.

Thoughts?
