If you're playing hardcore then go with Stormshield. If not, Spirit or even Splendor would probably work better. Of course, if you could get a Jewler's monarch of Deflection and socket it with some facets...
Artisan's Tower Shield of Deflecting? I have one...
(shop deflecting blue shield in 1.07 with decent prefix and you can larzuk for up to 3os and therefore an even better ATSoD)
It's usually either Spirit or Stormshield. If you need resists, you probably wouldn't need more than what Moser's with 2 pdiamonds offers. That shield also adds a high bonus to the chance to block and the block rate.
