When I started the Tornado cut, it took me a few days to get the knack of it. As stated above. over time your hands will adjust to the different positons the packet takes. However, I do this with two methods.
1. I keep doing 180 degree rotations with my right ring finger like you usually do.
2. I recently independently came up with another method - it's a little tough to explain. When my ring finger contacts the middle packet, I put it a little lower so when my ring finger tries to rotate it, the bottom right corner is blocked by the lower left hand packet. I continue putting pressure until I reach a point where I bring my right hand up just enough to let the packet spin 360 degrees due to the pressure I had built up. At the same time, I loosen the pressure between the corners of the spinning packet, allowing it to spin a bit better. It's hard to explain, but hopefully you guys get where I"m going at.
Hope this helps you out.
