As the title says; ALL plastic. No metal weight rings, so yoyos like the protostar (take that!) and counterattack and hot shot are out.
Sorry, the protostar is a GREAT yoyo, one of my favorites, but its overshadowed all other plastic throws.
Mine would have to be the 2010 Duncan Freehand, YYJ Spinfaktor HG, and 3yo3 Acryllion.
Don’t forget 3yo3 everyone!
