I think what you're going to hear the most(For Ascetic's, at least) is, first, get a new pair of H2H. Destroyers are pretty out dated now and there are some fairly easy-to-get ones out there in Abyssea(Taurine&Fruor).
Also, I would invest some time in getting an Atheling Mantle. It's a lot easier to get than you would imagine, it's a 100% drop off of Orthrus in Abyssea - Altep popped with the Key Item from another NM in Altep called Amarok popped with Tiger King's Hide, H.Q. Dhalmel Hide, and Sharahba Hide (or something like that).
Instead of Byakko's use something like Shura Haidate and try to get your hands on Tantra Gaiters and Tantra Cyclas/Kirin's Osode. And, personally, I would use Ire Torque instead of Chivalrous Chain, at least inside of Abyssea. And Anwig as above mentioned.
Also, depending on your jobs getting a Thunder Gorget would not be that hard at all. 10 Xzomit Organs, 5 Hpemde Organs, and 1 Yovra Organ. I went out to sea as THF/DNC farmed 5 Hpemde(Goldfish) then killed the big Xzomits(Squid) for those 10, the big ones in the "school" are 100% drop, then for my Yovra organ I soloed a HQ Yovra on NIN/DNC, wasn't difficult at all and ended up skilling up on it for the last 30% or so.
My current V Smite set, take from it as you wish.
