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. [...]
Gasquet's racquet has a massive buttcap, or it could be having his leather grip over-wrapped on the bottom. This clip of him re-gripping clearly shows the built up buttcap area.
