Synergy Caps

How well do they work and what size goes in a lyn fury?

they make it like hubstacks, you can do a pull start and stuff. it also adds weight so it pretty good.

Size 1 fits the Lyn Fury.

yah size 1, lol forgot about that

The plate is essentially a sidecap combined with a bearing seat. Bearing goes in, can spin. The touchable part is another cap over the bearing, that only touches the bearing, like string. When you grab this, the bearing spins, and you can hold the yoyo.

o yeah you can also use it for offstring indoors.
