Here is my opinion about everything that no one will care about.
I honestly don't see the need for a second belt, if I am being honest, since it will just be hot potatoed a lot in away, but I can understand why. My vote original went for the National Title followed by the TV Title, but I like the idea of PROTEUS belt a lot because you can tell a good story i.e. if your wrestler is a Submission Pro and your opponent sucks at them then it plays in your favor and if the other guy wins it told a good story.
As far as how to determine a who would get a chance at the new belt, I can't see any other way than a tournament of the sort, but like KoA mentioned that would be two in the same year and such, so that is but of rock and a hard place. So I really have no clue how that would work out.
I could be wrong, but if NFGW isn't cannoned with LDW then its belt shouldn't be used unless a merger or such happened and what have you because then you have to explain it and so on and so on. The idea of it being a Hardcore Title is interesting, but I don't know it is necessary as it seems like a TV Title can just do the same as a Hardcore title or even the PROTEUS belt do the same. Whatever happens, I will be for it.
Again, just my opinions on everything.
