I don’t have the ND Ultra, but if it’s like the Horizon Ultra, it has an excellent grind surface, that is somewhat negated by it’s light weight. They are both 63g or so. Note, I’m not saying it’s not a great yoyo!
Also, keeping in line with the “good for the most types of grinds” idea, you might consider the Space Krown Ultra. I don’t have that one either, but it has that same awesome finish and material, is 65g, looks like it has a decent cup for FSs, and has an IGR…
I wish I had bought one instead of the Horizon Ultra.
