What Nightfyre said. Your sets should be different, and seeing as gear or food that brings your max hp up enhances sublimation, your set should contain:
Refresh items
HP+ items
(if you're a sch, items that enhance Sublimation effects...but you knew that!)
On another note, Genbu's Shield would be a good item to work on for Sublimation if you're bored. HP+ through augments and PDT, if you're really worried about needing both at the same time
