DM/SD Slotting for Soul Drain

Dear fellow Heroes or villians,
I have been playing my DM/SD scrapper, and I have to say that I love it. He does so well and that overall I'm very pleased. I've been using a budget build for the character, but in communicating with other players I think that I might have slotted soul drain incorrectly.

Current Soul drain is Slotted for damage mostly with Scirocco, but I know of one person who slots with +to Hit buff, specifically a 6 slot of Gaussians.

My question is this:
When looking at total damage numbers and other effects of using the Soul Drain followed by Shield Charge; what is the best way to slot those two powers?

When I was looking at mids it seemed that slotting Soul Drain for +to hit buff made more sense since the higher damage numbers appeared on Shield Charge.

However I've been told that the damage buff on Soul Drain is fixed by the number of enemies that you hit and is not adjustable via sets, and that it is an error with Mid's that it calculates the additional damage in (I have the current Mids)

So when crunching the numbers what do you think?
I have Cut/pasted my current build so that you can see things outside of the vacuum.

I six slot a set of Obliteration

I have mine 6-slotted with Gaussians. The only reason I can get away with this is that I have the kismet +6 to hit IO and run at +66% accuracy from set bonuses, which caps my to-hit with Soul Drain against +4s. If I wasn't running such a high accuracy build I would go with obliteration as well.

I six slot with GSFC and never had an issue with it. The only time I've noticed a large amount of miss was on Nemesis who had veng stacked about 4-5 times. And really, even then a yellow or two instantly fixes that.

I six-slot with Oblits for a different reason >_>

When I pvp /dark MMs, I need to have as much +acc and +tohit as possible if I'm going to have a chance at taking them out, so I went with the set that gave me accuracy.

Also, I like the recharge bonus as well.

I used to slot a full set of guassian's because I didn't want damage as it killed my fodder for soloing AV's. After I pumped up the build a bit with PvP IO's, I think I actually slotted 4 recharges (yes, over slotted) to get the power as close to permanent as I could. I've always been much more interested in sustaining soul drain's buff then I was in the damage it actually does.

I'm getting an error when I click the DataLink? My Mids has the latest Update to it.

I slot SD with a full set of Oblits, and put the Guassian's into Focused Accuracy.
