best shield options

[talrave]

My assassin probably won't be using double claws so I'd like to know what are the best shield options for the assassin:

I figured stormshield would be best because of it's high block and great mods on it but are there any other formidable choices ?

what kind of sin are you?

[mephiztophelez]

stormshield is the "usual choice".

Sanctuary can work wonders, so can Gerkes Sanctuary on an iDR rig.

mosers blessed with ums or diamons does'nt suck either...
