Rings, completely.
Aside from the LotR connection, you can do absolutely anything
with them.
Want a charged magical item? Make a ring.
Want a use-activated or always on item? Make a ring.
You can put every effect you can afford into one little band
of metal, so you can save the rest of your slots for whatever you
pry off of corpses.
If someone _actually_ manages to steal it, just make sure you
have a 'called' enhancement like the armor one from DotF, and
just summon it back.
