Val's Demon/Pain Tankerminding Build - comments and advice, please!

I understand that the -res to the whip powers is pretty spectacular, but it eats tons of endurance, which affects my bottom line of things such as toggles (leadership, suppress pain, et al).

I've been trying to get my build to work out with the right balance of survival, team assistance, dps.

If I could get all of that at once, that would be grand. What is the general consensus on all this stuff? (attacks versus toggles versus recharge versus defense)? Is IOing about the best way to go to get there?

Cr4akc Whip is teh real big ticket one. The others are fairly comperable to other ST attacks in any set. Of course, the point is that their DAMGE is not comparable to the attacks of other sets, but thats not what we took them for, really. I definatly recommend endurence reduction in Crack Whip.
