I was just noticing that the weight of a lot of newer yoyos has been increasing. Not that there wasn’t heavy throws in the past, but with the width of some yoyos approaching 60mm, it seems like they are more common. My last throw was the Kyoto with a weight of 70g. It’s not really noticeable on the sting, at all.
Anyway, I was just wondering what everyone’s take was, on heavier throws.
I’ll throw anything but crappily. I find the heavier throws help me throw a bit less crappily. So I am ok with them.
I don’t mind mainly because I’m a big fan of heavier throws, around 66-68g. Kyoto is really interesting because you’re right, it feels a lot lighter. Atmos throws tend to have that quality about them, the ti throws especially. The Polaris is 67g I think but plays like a dream, same with the Hamr, around 66-67g but man does it move.
I’m assuming a lot of the heavier weight has to do with more material since yoyos are just becoming bigger, and more power. Nice topic.
I agree. The Polaris plays like a dream. A few of my titanium’s are like that.
Shape and width play a huge part. I remember back in the day we used to put rubber rings in our FHZs. I never weighed one, but they had to be around 75 grams haha.
63-65g for metals, 66+ for plastics
It’s interesting, it seemed like when I first started, everyone was after sub 65g throws. There’s still those, but lots of heavy boys too! Atmos is good example with the 59.5g Noma and the 70g Kyoto
I have yet to try the Kyoto, but I did get a chance to throw some of the lighter stuff from atmos. They are super well made and great shaped, but just not my cup of tea.
I feel like 67grams is the sweet spot
We prefer things on the lighter side 
I love the 70g mark, my turning point naja is 70g and summit 2 with RSM side effects is 71g. Can’t say the weight is felt much but the spin times it gives monos is amazing
I wouldn’t think weight added to the Center via SEs would increase spin time.
Yeah, my friend and I was curious how it effects play outside of just hubstacks and with a center grooved bearing for testing on sleepers it has about a 40 sec longer spin time than without
Edit to add more context, 4 se was tested and from best to worse we have. RSM, ti kisses(? Think it’s called), engraved s2 caps, ultra lights
I prefer 66 grams as being perfect.
More momentum in the throw leading to stronger initial spin?
Yeah, but that weight is pretty much on the axis or rotation.
To elaborate, the heavier weight creates greater acceleration on the throw.
I think I had this discussion with someone a few years ago as the width game started heating up. Really what you are concerned with is the moment of inertia, so as you go wider the weight naturally has to go up to be able to achieve a similar moment of inertia as something narrower. When done correctly you don’t notice the weight on the string, but you’ll feel it more in your shoulder, especially if you’re going horizontal.
Yeah, but if the weight is truly on the axis then r=0 and the moment of inertia wouldn’t change. I suppose some of the weight of a SE isn’t strictly on the axis, but r it’s still quite small.
Perhaps you are correct. I’m no scientist.
