I've been away from here for a while... I probably have to read through this entire thread to catch up!
I officially joined "The Mighty One" and moved my rig to their studio. I am now running 2x 210 cabs and my ideal scenario is finally realized. One 410 is running a dirty channel from my Sansamp RPM and the other 410 clean channel from my 4-Pro.
I plugged in, warmed up and the rest of the dudes:

It sounds like a 8.7 earthquake (I know as I've been though one). Absolutely MASSIVE!
The band amps everything to get the stage vibrations happening and also we use In-Ear monitors which is simply awesome!! On that note, I am looking for a Shure PSM200 if anyone has one and selling, let me know
Feel free to like the Mighty One FB page and spam with Spector family goodness!

We have a show coming up on April 12th, my biggest one thus far (that's not saying much...) which I am VERY excited about as it's in a really cool old theatre and so there should be plenty of ambiance!

I'll make sure to get some videos of that show and post them up!
Cheers everyone!!
PS.
I am planning to do a video of a cool little exercise that I've been working on to work the 3 finger plucking technique!
