You can do whatever you want with any unicycle you want. You could probably do freestyle on a coker if you wanted to and were good.
Here’s how it works: get the lightest you can afford. If the lightest you can afford is 10kg, and you’re willing to accept that, then you WILL make it work for what you want to use it for.
Getting a heavy unicycle and getting good with it just means you’re better than the guys at the same skill level cheating with light ones.
