It’s a wonderful yoyo. Many people like it a lot. You can indeed silicone it if you want, just make sure to make it either flush or raised, not recessed, if you want it to last for any decent period of time.
i think the best fundaMETAL is the Dv888. I think that’s the best first full metal, i would even recommend it over other really good full metals. (Axiom, Chaotic, Vendetta, etc)
