A very interesting handbalacing act by Andrey Moraru.

Found this to be quite different from regular hand balancing acts. I also noted that he tends to "curl" his fingers when in handstand , do any hand balancers here have experience with the technique?

Andrey has huge hands, but yes, applying finger pressure gives you a wider base to balance on.

I actually try most of the time to balance through my palm with flat hands(especially on two hands) but end up curling my fingers when I fall slightly out of line and have to put forth some effort to bring it back.
