only yoyos I know of that are that big are Jirorian, Dreadnought (G, and normal), and the H5.
Never used an h5 personally, but I have used the first two.
just my 2 cents, the Jirorian is a great yoyo that plays a bit lighter than it actually is. I think it’s like… 71g? something like that. but it plays like a few g lighter. It’s really stable (of course… it IS crucial. :P) and it’s just a great yoyo. A couple people who have used mine though didn’t really like it.
I very very briefly used a normal dreadnought, so can’t so much about that. I think it was good though.
The dreadnought G I used for a few minutes. It’s REALLY heavy. like… ridiculously so. But it’s also incredibly smooth, and flows really really nicely.
