I am interested in one if so
If you don’t mind spending on a high end throw, the Elysian by Eternal Throw provides some long spins without being oversized like the Horizon. YYE has a few of these left.
The Horizon is one of the most stable and longest spinning yo-yos on the market so you won’t find anything drastically better in either of those regards.
The CLYW Sasquatch is more stable, spin is relatively similar.
The Shu-Ta is a more stable Shutter. If you want stability my go to is the Onedrop Chik!
You would be hard pressed to find a yoyo more stable than the horizon, and the shutter is definitely not IMO.
Yoyofactory Cyborg 2.0 not similar but more stable and better spinner.
iYoyo Steel, it plays like a bi metal Horizon.
