what weapons and which skills do you use, that might help us suggest thing for you.
additionally how much magicka regen are you running atm?
in light armor a magicka regen of 1.5k is surely something you want to achieve.
depending on you skills and weapons, i would rather suggest, that you run another set instead of willpower. for example, if you are running sword and shield backbar, you might consider lich jewellry and sword and boar. then you are free to use what weapon you wish: firestaff, lightningstaff or dual wield on fronbar.
a good alternative set for magplar dd's is warmaiden as long as you deal damage with class abilities like dark flare or jabs.
