That might also be where the Metal Replay came from? A mystery box?

Yeah - the Metal Replay was from a mystery box in 2015

Yes! Replay Pro looks like it’d be sweet! I like the profile. Right up my alley! Guess YYE is not selling it anymore…

He got back to me with this:
All preference. Provides the same weight distribution but some people prefer a couple extra grams. Usually adds slightly to the spin time with 7075 but with today’s yo-yos you’re usually not hurting for that.
Assuming literally nothing else on the yo-yo changes except the material going from 6061 to 7075 (and I’d assume 7068 as well) – it’s heavier.

I often see the sentiment expressed that today’s yoyos have “more than enough” spin time, yet to my mind spin time is like battery life: there is no such thing as “too much” or “more than enough”.
It’s like people who ask, “Who would ever need more than N hours of battery life in their smartphone/tablet/laptop?” Believe me, if you come up with a battery that provides Nx4 hours of life, people will find a compelling use for it.

I think they mean “to do a reasonable trick routine”. Related to the “one throw” video trend that went around recently.

Philosophically speaking, “reasonable” does not have a useful definition, AFAIC. No performance parameter should ever be based on such a non-metric. There are only minimum, maximum, and average values, and the field of design and engineering should never settle for a maximum that doesn’t continually improve over time.

I think every “reasonable” person would understand what was meant 
Remember the old supreme court statement about “I know it when I see it?”

The context for Justice Stewart’s statement isn’t even remotely comparable to a discussion of performance parameters in an engineered product.

Right, but “reasonable trick routine” is, hence my statement.

“Reasonable trick routine” is not a useful metric since it has no single, unchanging definition that can serve as a design and engineering goal. It is, by nature, a moving (and highly subjective) target that denies makers the luxury of resting on their laurels.

I want to try the metal Replay. Not a huge fan of the plastic and the metal is slightly smaller.

Good luck, it was a limited 2015 mystery box only item per the above. I bought the first one I saw come up on any B/S/T in quite some time, same strategy I took with the Shu-Ta 2.

Kuntosh time! Like with the other One Drops, I removed the side effects and bearing and measured just the halves individually.
7075 QV
29.64g, 29.58g = 59.22g
7075 QV
29.67g, 29.72g = 59.39g
7075 QV hardcoat
30.10g, 30.04g = 60.14g
6061 Kuntosh
30.33g, 30.32g = 60.65g
Bucking the trend here. 7075 should be heavier, so they tweaked it to be almost the same weight, even a tad lighter.

Plastic Wedge (glitter, full C bearing)
66.68g
Plastic Wedge (half-spec C bearing)
66.23g
Delrin Wedge
67.54g
Weighed without string, but with bearing and axle.
As far as differences… definitely fatter rims on the plastic (only in horizontal width, the parts extending down on the outer cup are the same exact diameter), but where the plastic rims stay perfectly flat on the outside, the delrin outer edges cant distinctily inward. Clearly delrin is denser, stronger, heavier. Overall these two are quite similar, diameter and width are 100% identical, but the angle inward toward the bearing is necessarily a steeper angle on the plastic because of the fatter horizontal width of the rim on each side.
There’s another difference between the two plastics, the aluminum hub on the transparent one has bolt-like hexagonal sides attaching it to the plastic whereas the gold glitter hub is a circle with serrated edges.
I don’t have a monometal Edge but if I get one I’ll compare it as well!

In today’s thrilling episode 
That’s right… it’s LINKX time, people!
We have poly hybrid, nylon, and poly. I measured with bearing but without string.
- “premium” → 63.62g (YYE says 63.75g)
- nylon → 59.00g (YYE says 58.64g)
- poly → 62.13g (YYE says 61.7g)
(note that my poly LinkX is set up responsive, with a slim C bearing, so we should probably add about half a gram to that one.)
I’m still mystified as to why the weight for the premium version was kept in the central hub. Usually for hybrids they put weight rings on the outside 
. I can’t see any difference in the shape or width other than the metal center. So yeah, Premium LinkX plays like a slightly more center weighted, heavier LinkX. It is less heavy than I thought it’d be though, basically +1.5g?
I don’t mean to come across as negative, I like the LINKX, that’s why I have three of them … honestly I think it’s a better overall shape in plastic than the Wedge… come at me, bro!

Yo i can’t believe nobody has mentioned YoyoFactory’s Dream line of yoyos that was based off this exact same question, How would the same shape play when designed with different materials. Here we have the Aluminum Dream, the Nightmare (Bimetal) and the Titanium Dream.
The only specs that differ are weight:
- Al: 64.9 g.
- Bi: 64 g.
- Ti: 65.3 g.
The design differences of each material are very clear here. Al has beefier rims than Bi and Ti. It’s interesting to see that all of these use the same axle lenght and the same nipple for the axle. I would love to see a cross section of this yoyos.
Also, the engraving on the Nightmare is lovely.

OMG I didn’t get the dream → nightmare connection at all! That’s fantastic!
