I tried a metal cream, not the production though. (He had hubstacks on them.) They should be out in about a week, and 100$. Anyway, it was a light yoyo. Lighter than my pgm. It was smooth, and had a great thumb grinding lip. It is a raw yoyo. Nice for smooth tricks. Nice for arm grinds too! I only played with it for almost exactly 30 seconds so that is all I know. 
Cool! It must of been a 30 seconds of joy! ;D
So true!
