No roadies - I wish! Another local guy kept adding 15's to his rig, and so it became a mini "arms race" for a while between him and me. A friendly competition of sorts.
Most of the time I would just use 2 of them because they wouldn't all fit onstage. Yes - they are SVT-3 Pros loaded into SVT-CL housings. When I got the first one, I didn't have enough cash to get a 2-Pro or a CL, so I opted for what I could afford and figured I'd dress it up a bit. I actually dont run them as loud as the look - I'm pretty sensible about my stage volume
