Huge fan of the Aeon v4 for spinning and duelling.
Flamberge pommel looks fantastic on a Dominix! Just do a quick forum search on Samhain and his Dominix.
I use a War Glaive pommel on my Aeon v4 to balance it out, and with a 32"blade it is right on the edge of the emitter, making it a perrfect balance when you hold the saber at it's upper chokepoint. Wich is what I usually do.
If you go for a Aeon or Dominix v4 considerr the windowed emitter. I think it is beautiful, it doesn't hurt my hands, but I can imagine that it might. It's absolutely not as sharp as the v5's, but still, something to consider.
And I think a AV-switch is an option, I dropped my saber so often that the plastic guarded switch broke. I think the AV is a bit tougher.
I get your thougths on the meditative part, that's one of the reasons I started with martial arts. I'm not the one who can sit and stare into nothingness for a very long time. But give my body something to do and I'll get in some sort of meditative state. Spinning can be an excellent way to do that. As a TCC instructer I have a few more thoughts on that, especially on the sense and nonsense that is being sold nowadays, but that's an entirer different discussion.
But if you're interested I might even do a little rambling about that in the future.
Anyway to end my post, I really really love the Aeon v4, would definately advice them. Great look, great balance, great hold and handling. And of course a few pictures so you can compare the light and the darrk side.
