With brawny and Black Belt, you'd already be pretty much full-timing -10%PDT which is quite nice anyway.

Other particular items of note are: Augmented Dark rings from abyssea konschat gold chests (max 6% each) or Defending Ring (10%). Twilight Torque (5%) or Wiglen Gorget (6% -PDT +6% MDT). Either Fugacity Beret (1% PDT 12 eva) or an augmented Genbu's Kabuto (3% PDT 8 eva) or Arhat's Jinpachi +1 (6% PDT). Augmented Kirin's Osisde (5% PDT 7 eva) or Arhat's Gi +1 (9% PDT). Melaco Mittens (3% PDT). Molluska Mantle (5%). Darksteel Subligar +1 (3%). Plumb Boots (5%) or Darksteel Leggings +1 (2%). Colossus's Earring (1%).

Also Sheltered Ring is worth noting, as it will make 5/5 Shellra 5 give 29% -MDT, meaning you only need 21% to cap it. It also gives 1% regen while equipped if you're going for an idle set too. If you are, both Genbu's Kabuto and Kirin's Osode can be aug'd with regen as well. Note that these aug's can take a while and cost quite a bit to get.

If you can't get hold of any of the -PDT items, replacing them with Kacura/+1 for eva is a good second best.
