I’d have to agree that mine isn’t “dead smooth,” but then again, most metals aren’t either if I’m really nitpicking about it. The minimal amount of vibe in my Skyva can only be noticed when doing a fingernail test, otherwise it feels dead smooth during normal play; much like most metals that I have owned/played. As for during finger spins, there is a bit more “vibe” as the machined innermost cup area isn’t perfectly smooth.
It is incredibly difficult for most metals to even be considered “dead smooth”, at least by my standards. Only a handful of the 50+ metals that I have owned would be classified as such, most of those being mint right out of the box. Most OD metals have been dead smooth for me, at least ones with SE’s; my Sovereign and the Citizen that I had both had tiny amounts of vibe. The two Draupnirs that I owned. A TP Palpitation. My Evora. The SPYY yoyo’s that I’ve owned; Orbitron, Supra, and 3 Addiction v2’s. My Anti-yo Bape.2, Vis, and Stealthzilla. Two YYF Cyphers, and both a Space Cowboy and Cowgirl. My Masamini. And 2 G2 Marvels. Otherwise everything else has had a noticable amount of vibe if you put it to the fingernail test, but mostly it’s completely unnoticeable during play.
With all that being said, my Skyva is one of the smoothest plastic throws that I have played. My OG Yeti is also incredibly smooth for a plastic, and the smoothest that I have played is probably a Regen which is machined POM. I guess that I have gotten lucky with all of these, as they’ve only had as much “vibe” as most metals, where you can only tell on a fingernail test, but otherwise play very smooth.
