As for EEE, I use void and take a bit more damage than you'd do in bandos. But void is still faster kills. I've tried a lot of different combos and found that void, CLS and EEE as spec weapon works best for me. I'm sure you could easily make it work with Korasi's, but I'm not really sure how much it would increase KPH.
Don't really have time to play at the moment so I'd have to test it later some time.
Well, i don't have ss. But if you do, you can probably outheal how much the skeletal wyverns hit for.
If you're using overloads, you can always bring a few brews just in case.
Korasis are sweet cuase they always hit and the skeletal wyverns have pretty high defense.
