I’d also say go for it.
Try it with balls first, they don’t get in the way nearly as badly as clubs.
Remember, to be able to do anything while idling, you should be able to idle without relying on moving your arms to maintain your balance.
A good way to practise this is to fold your arms, either in front or behind your body (do in front first).
You’ll probably find it’ll shorten your idling runs quite a bit at first.
Relax, keep your weight on the seat (and not on your leg) and remember to breathe.
Also be sure to start practising idling with your other foot as well.
The earlier you start, the easier it is.
I’m with Gild. Juggling and idling are two very different rhythms and the hard part is doing both at the same time.
However I find using clubs much much easier than trying balls on the unicycle.
You have to switch your concentration back and forth from the juggling to the riding. For those milliseconds when you are thinking about the riding the clubs are easier to see peripherially and easier to catch.
BTW: Idling is SOOO much easier on a giraffe, so is juggling.
Something else to bear in mind is that you don’t have to move all the time.
Doing pretty short little still-stands in-between the forwards and backs helped me quite a bit to get my juggling pattern solid.
And yeah, I can still idle one-footed and juggle 3 clubs on the raffie.
I can’t even dream of that on the 20.
