Steel plays really well… I like it. I’m no expert, a beginner at that, but it moves! A little difficult to keep on plane at times but I think that’s the object of this guy, a practice yoyo. Missing a few strings here and there.
Never having played a 66% or smaller I can say its super weird going back and forth. A “normal” throw size feels gigantic!!
This thing is also a lesson in physics. Really different feel, the way the weight is concentrated on the string. Butter is near identical in weight but feels so much lighter after playing with Steel. It also HURTS a LOT when you crash it into your hand. 
Its going to be nice to be able to carry Steel in my pocket!
