Actually when this subject first cropped up in a tango forum/discussion list, and my hand position was referred to as odd/quirky, I did a little research and found that my hand form is very similar to the following dancers:
Gavito (when not doing a show) (deceased)
Dany 'El Flaco' Garcia
Omar Vega (deceased)
I only found Julio Balmaceda's hand form to be different, leaning more towards the 'waiter with a tray' form...
All these guys are the examples from whom I draw inspiration...
