Okay, sorry for the confusion, my fault.
Let's go with this, and I've edited the original post to reflect this:
In strict industry terms, the v1 is the "Hero" prop and the v2 and v3, etc are all variants of the v1. But in ROTJ, which saber best represents **your** "Hero" Luke lightsaber.
I didn't mean for this to be an argument of "Is the v1 really the v1 or is the v2 more of a v1?" But rather which one to you best represents Luke Skywalker's lightsaber.
