Btw, I found it useful to make the buttcap slightly larger, otherwise I find my grip slipping back to "old fart" after a lot of backhands.
So I wrap my buttcap with 3 layers of overgrip. So you might want to experiment with that.
I've heard that Fed uses an oversided buttcap (for his undersized handle), and I suspect Gasquet does too, as well as other 1-handers. But I'm not sure.
Our hands are going to be different, so do what works for you.

Yup. I used to use an extreme eastern grip (steak knife style) to close my racket face, but realized I didn't have to if I just moved my heelpad instead.
Another benefit (main benefit?) to a low heelpad is that the racket will form a tighter angle with your arm (See the Mauresmo picture for an extremely sharp angle). This makes for a more stable hitting structure.
