having trouble with a couple of Ben's tricks

The first trick I’m having trouble with is stop n go. When I throw the yoyo up usually it doesn’t bind, if it does, sometimes it goes to my left hand, and even if it goes to my right hand I have a hard time catching the yoyo.

The second trick I’m having trouble with is spiderman. I can’t get the yoyo to land on my hand without flying off. Should I throw the yoyo down more, or to the left so it is more horizontal?

I am using a flight and I don’t have gloves.

Any help would be appreciated.
