What are the differences?
The PSG stands for “plastic Hour Glass”. The shape is generally like that of an hourglass. It’s heavily rim weighted, big catch area. Very much an H-shape. It’s not a speedy yoyo.
The Asteroid is a lot faster, bigger, and more aggressive as a player. It still has a good catch zone. The sharper design cuts through the air.
The PSG is more well rounded. It can handle 1A, 3A and 5A. The Asteroid is more of a 1A beast.
Both can have vibe, both can be siliconed, both can benefit from bearing upgrades.
