Ok some quick thoughts… and a visual comparison of the Cold Fusion with the Confusion.

Get it? _Con… fusion… Cold… fusion…_ ❗❓

Some obvious visual stuff first.

- Matte / blast finishes are superior to glossy finishes

- It is clearly wider and more butterfly-ish “gt” – the regular Confusion is _almost_ equivalent to an old school Cold Fusion GT!

Less obvious stuff after playing them both for a bit:

First, the starburst style cork response is surprisingly a bigger negative than you’d think. With a flat narrow bearing, the string is gonna rub against those, and when it does, you get some rhythmic thrumming from the built in surface irregularity. I guess the designers were thinking “hey this is like starburst but more betterer” hence the influence? :thinking:

Plus it’s cork, not sure if that matters a whole lot but you do feel the “bumps” of the starburst-esque incursions of metal into the cork in play and it sure doesn’t feel great compared to now standard silicone response pad rings, that’s for sure.

Second, there’s a whooole lot of center weight here.

As you can see

There’s

- a captured metal nut
- brass spacer
- aluminum cap
- aluminum “nipple” protrusion
- big, thick threaded metal axle

All that adds up to _much_ center weight.

So on the whole, I wouldn’t say the Cold Fusion stacks up to modern metal responsives particularly well. I would not go out of your way to get one of these unless you’re super interested in yo-yo history. Oddly enough and perhaps paradoxically, I’d say the plastic Turbo Bumble Bee and GT feel less anachronistic in play, perhaps due to a different weight distribution in plastic… not sure :thinking:
