I find it far fetched to believe that Razor would give his Nen Ball a quality which would decrease the force of the impact, since the rubber texture would absorb quite a lot of the energy. Now, If I understand what you're saying correctly, you believe that Aura has no mass until it has been converted into Nen... That's what I'm saying! Mostly anyway. Aura has no mass when it is inside of the body, hence Nen users don't weigh obscene amounts, and when they convert their aura into Nen, it then Gains mass. Mass is matter and matter has a state; therefore that state is plasma!
