MK1 and Spinworthy recently teamed up again to make the Plasm, a polycarbonate version of the RBC. This new version of the much-loved throw features a tweaked design that works better with plastic and is available in a range of cool, translucent colors. I was lucky enough to have MK1 send me one to put through its paces, and I can say that this yo-yo is an instant classic.

I’m going to preface this review with the fact that, unlike many, I am not a big fan of the RBC. It’s a beautiful throw, but I couldn’t quite figure out where it “fit” as a yo-yo. Unlike the wooden Blood Cell, a Spinworthy original, the RBC wasn’t made for fixed-axle play. It also felt quite awkward as a 1A responsive yo-yo. Again, I’m in the minority here, but other than how cool it looked, the RBC just wasn’t for me.

The Plasm is a completely different story.

I could immediately tell upon my first few throws that this yo-yo is far more capable. The catch zone is a bit larger, the shape a bit more forgiving, and it plays both 0A and 1A styles beautifully. It’s super comfortable in the hand and has a wonderfully satisfying response. You can feel the seam of the cap more than you can on the RBC, but it is by no means a problem or a distraction. The changes MK1 and Spinworthy made to take the RBC into the realm of plastic made a world of difference in how playable the yo-yo is.

Whether I’m Makin Da Zines or Skinning the Gerbil, the Plasm handles it all with ease and comfort.
