Hi Zanev
Catching first - If you focus your vision as hard as possible on the centre point of the staff this should help you catch it much easier. The reasons for this are:
1, This part of the staff is spinning the slowest,
2, This is the best place to catch the staff (as a beginner)
3, If you are trying to throw the staff at night and you focus on the flames rather than the grip the contrast between the brightness of the fire and the sky behind it make the staff harder to catch.
Throwing with spins should be pretty easy, I would try it from a figure of eight with your hand slightly off centre to the outside to give you a bit more leverage. Make the throw so it is parallel with your shoulders. The staff should leave your hands as it passes the front of your torso.
You can catch it in the same hand and go back into a figure of eight, or you can throw it to the other hand and go into a reverse figure of eight.
I hope that helps, if you search "staff juggling" in YouTube you will find lots of different staff throwing vids.
