What cab do you run your VR with usually? I was gonna ask you to post a pic but I see you did already, nice!
I'd love to compare the new sealed 610 to the older ported PH610 and hope my dealer orders more then the 115 they have in right now. I love the PH610 but don't use excessive low end and I feel I don't really need the cab porting for the tone I'm looking for. My main issue with the Ampeg 810e is the tolex wear and handle placement. If the traditional 610 gets a similar tone then I'd much rather get the build quality of Mesa over Ampeg any day.
Here's a picture of my rig.
