I don’t think a 4 year old swinging around a metal yoyo is a good idea.
If you have a surge and order a classic your little bro will be set for a long time.

Guys, he’s only 4
my cousin is 12 and after 2 hours of practice she still cant do a proper sleeper… She can barely do gravity pull
I suggest getting a yomega brain and a yoyofactory ONE. The brain will come up automatically for starting out and the ONE will help him when he gets more advanced. Comes with a responsive and unresponsive bearing.

Jake Elliott:I don’t think the size of the classic will be a problem. Small hands might not be able to wrap all the way around the rims, but you will be able to get a good grip more towards the middle.
Getting a yoyo with a small gap is quite important in this scenario. Not only because the yoyo will be to be responsive, but also because a four year old will have to use a short string, meaning that binds/winding won’t be nearly as tight in a larger gap. The thinner the gap, the tighter the binds. Very important.
