Yes the weight is right. But he also admits the balance is still not correct. And yes I have fought using rattan. Never feels right compared to the real thing. I have found the new nylon swords are better. They have a better balance. I still use hand position and grip to know where the blade is. Not weight.
I know where my hands are with my eyes closed. I know where my blade is because I know where the grip is. I know where the grip is pointing. I have never found that this fact changes no matter what I have in my hand.
If I remember correctly, they've never actually confirmed the blades as being weightless in canon. That was something that was created in the Expanded Universe/Legends, so it can go either way when it comes to debating about it. I've always believed that one can simply become skilled enough to wield a lightsaber through proper training, even without the Force, as General Grievous is a perfect example.
