Yup, read most of it, Lots of info,, just discovered a new way to use the HD500, has to do with routing, long story short, using A path and placing Mono effects and amp in A path and Muting B path.
Explained here:
http://line6.com/support/topic/2033-pod-hd-500-500x-new-routing-schematics/I did a A/B comparison with the 11R, using same settings(as close as I could get,using same amps)and surprising they were both good sounding just different.
For my taste, the 11R sounded a little "livelier".
I haven't used the HD500 for months, because I bought a EV elx112p and have been using that with the 11R. At that time, I tried using the HD, but sounded weak. Just recently, happened on a tip about using Path A and tried the HD with the EV.
Still the HD is a very complicated unit when it come to paths, inputs etc. I find the 11R easier to maneuver. Plus its much better sounding with my studio setup.(Mackie HR824's,older ones) and works well with Pro Tools. But my favorite amp sim is S-Gear. But haven't figured out using S-Gear for live yet.
What part of the info interested you? Anything in particular?
They both are fun units to create good guitar amp tones.
From what I see here, on this forum, you are the meambobbo of the 11R.
Anyway, fun stuff.
