I've only seen grounded and blastproof, but im fairly confident they can be alkaline and inflammable as well.
Playing like an idiot at the moment, been running round with the bee for a week. I'm gonna see if i can track down an Alkaline or Inflammable Version of a tediore shield. --- Did you know that if you use slang more than 80% of the time you may not have been properly educated? Of course you didn't.
The impaler! Recharge delay 1.99 and a capacity on 49k, at least that's my version. Downside is the recharge rate, about 4k
Any decent shield with Hyperion parts can get a pretty low delay. Tediore and Dahl parts also give lower delays, though not quite as good as Hyperion. Also, do you mean 49k after skills/badass rank? Highest I could get was 43k capacity with 1.99 recharge. --- http://img356.imageshack.us/img356/8325/scrunchface2copyfx0.png http://www.xboxlc.com/cards/default/alle5.jpg
