Any advice on slotting shield charge?

I'm kind of new to the world of brutes, but recently I've been playing an SS/SD brute and he's amazing. I've mostly been doing farms and such to solo lvl him (since everyone on earth is doing BAF 24/7 XD) and I saw recently that I was hitting the 400% damage cap for shield charge almost the whole time i was farming. At lvl 41 with no enhancements but nearly full fury, AAO, and x2 Rage, I'm doing something like 310-20 damage, which is fine, but I was hoping to get a little more bang for my buck. Does anyone have any ideas about the best way to slot shield charge for best damage?
Should I frankenslot it with damage procs and end redux/recharge and let rage take care of the accuracy and damage %? I know there was a nerf to SC a little ways back, so am I pretty much looking at what it's gonna be like from now on?
If there's a thread on this subject already let me know,
otherwise any input is appreciated
Cheers,

The slotting I see most often is 5 pieces of Scrioco's Dervish ( All but the proc) and a common recharge IO.

That gets you 89.5% damage enchnace and 84.31 recharge after ED and nets you the AOE def bonus that you were likely wanting on your way to the softcap anyway.

franking with procs and end/rech would be pretty good i would guess. Most of the time i see 6 slot oblite for the def though.

yep, 6 slot obliteration. it's not up so often that the endurance makes much difference.

Desired set bonuses would depend on the rest of the build. Maybe you are over the defense soft-cap and don't need a certain type of defense. Maybe you passed the rule of 5's on 5% recharge, making it tough to justify an Obliteration set. It would be hard to give truly good advice without seeing an entire build. All we can do is tell you what sets are good in general, but they may not be the best for you.
