Yes, they are quite big....205mm from my wrist to the tip of my longest finger. Maybe I should try wearing some gel pad track mitts or ski gloves. After all, I'm only dangling, not twirling about.
Yes; I think that pushes them into the larger end of the spectrum. IIRC 195mm is considered about average for blokes.. mine are about 190mm. As you say, no reason you can't use gloves.
I have massive respect for those who can twirl; considering the amount of strength required just to maintain static holds, that and the coordination required to launch yourself about on them must be insane!
