My key-fingers (for lack of a better term) are pretty consistent. I hit the 'b' with my left index finger and the 'n' with my right index, and everything else just follows from there. Here's hoping I meant the index finger, anyway.

Either way I've never been taught anything 'professional' about touch typing. I just do it a lot, I'm on QWERTY and I type 120WPM+. I think DVORAK is probably a heap of crap.
