Sorry, the list is seriously out of date and was original made around the start of 2.3 when PvP gear was a single secondary + Morale.

But from what I can tell the Det/SpSp BiS for WHM would be the following:

Swanliege Cane or Thyrus Novus/Nexus (Det/SpSp)
Swanliege Hood or Swangrace Hood
Swanliege Coat
(Augmented) Ironworks Gloves of Healing
Swanliege Belt
Swanliege Hose or (Augmented) Ironworks Slops of Healing
Dreadwyrm Shoes of Healing (Crakows of the Divine Harvest make a decent filler only loosing 4 Det compared to the dreadwyrm)

Accessory wise the Vit Det/Crit accessory set is your best bet.

Hellwolf Earrings of Fending
Werewolf Choker of Fending
Hellwolf Bracelet of Fending
Hellwolf Ring of Fending
Vortex Ring of Fending
