Here’s a great thread made by Spence that I generally agree with.
The leaf is better than the chief; it’s meant to be.
Also confirmed by Steve that summer tires are thinner than snow tires. Most of my CLYW yoyos have arrived stock with Snow Tires, and they almost always stick into the groove. Summers don’t. Almost never had this happen on non-clyw yoyos unless it’s a yoyo from BST and the last owner doesn’t know how to pull the clear backing out of the groove.
