Can anyone identify what this is a proto of? Or what yoyo it is?

But how does it play?

Slow. It weighs a ton.

It does weigh a lot, but it’s not that slow.

I meant I like it better for slower, more relaxed play.

Ah okay. I agree with you on that. What surprises me is the proto is great for horizontal, unlike the H5 which weighs about the same.
