I would think wavelength would affect grinds, but i’ve never thrown a yoyo with it. is it rough or is it just a picture that you can’t feel?
My super g and when I had my severe were both wavelength edition and I have found they grind good maybe even better. I say this because they just have a tiny bit of a powdery feeling. Thats all.
Laser engraving should make grinds better for yoyos that had no surface treatment.
Like dingo54 said, it has powdery feel that lessen friction on grinds.
