Fair enough. Hovering is definitely harder than forward motion, because among other things the tail boom acts as a weathervane during forward motion. But hovering is still easier than standing on a basketball. I've done the former, and I can't imagine even trying to do the latter.

Are you rated for the Basketball? How many hours have you logged on the basketball? /s

I got my "single basketball on grass" rating a couple of years ago, and have been meaning to schedule a checkride for my "single basketball on hardcourt" endorsement for a long time, but honestly I don't know when I'd ever use it.

Exactly. Flying a moving helicopter is not hard. A helicopter is much more stable while moving forward than while hovering. (And for the record, I am mainly a fixed wing pilot but I have also flown a helicopter.)
