Did anyone think about trying BOTH hands?

I have average size hands but I can reach a 10th with my left. What was interesting was ........I can reach that 10th with my right also but NOT as easily as with my left.

It's known that Rachmaninoff had hands the size of hub caps. Look at the complexity of his compositions.

and see.......

What is the average hand span for a pianist

Just how massive was Rachmaninov's hand-span? ...
