Stormshield is great for Dr but it has a HIGH strength rating at at lvl 90 on a sorc requires some 220 dext. Warped, whos my max DR max block sorc, ends up with 1450 life and 900 mana with her own bo. Fun character to play still. The DR makes up somewhat for the lack of health. Potting with energy shield is good too
Best bet is probably Whistans shield ( http://www.battle.net/diablo2exp/ite...ml#orphanscall ) with an ITH rune if you have enough mana (15% dmg goes to mana) or an ELD rune for a slightly better chance of % on the shield. You probably wont need a lot of dext with this item to hit a decent block.
