I just got one punched up for my younger brother, who throw it with two fingers. I however throw it normally. A few comments about the ball...
I would say the reaction is far from jumpy on a normal condition. I played on a typical house shot for a couple games with this ball. Although it was a pound less than my others I got a pretty good feel for how it moves. Btw the ball was only a 1 inch pin, but drilled on a 45 deg from the cg, with the cg in palm. That put the pin below and a little right of the ring.
The shape of the turn was a slow controllable arc. I would caution against this ball if you are looking for something to swing coast to coast, but I think this is an excellent ball for playing down and in, or something like 15 to 10 or 10 to 5.
The hit is regular, nothing special, doesn't hit like a marshmallow. I think I might get one of these for myself for lighter to medium conditions. Hope this helps.

Buzzsaws are very, very dangerous.
