For juggling on a unicycle I would think that a more open pattern
would work better (juggling by gripping closer to the knob rather
than the middle of the club).
I can juggle either way, but I can’t ride a unicycle at all yet.
Juggling with hands closer to the middle of the clubs tends
to increase the speed of the pattern (a lot, for me… if I
want to go really fast I do it near the middle)
Double spins I tend to do with a grip nearer the end knob
