The Alfaerie 'duke' image is a good King-like symbol. Jean-Louis uses it in his games for Prince, which is a non-royal King that can also make a noncapturing double-step forward. Other authors often use the 'guard' image, even though that was intended for KAD. The 'man' image is not very popular.
Note that image and name can be independently specified in the PTA. You don't have to use the name 'Duke' just because you like hat symbol. Jean-Louis calls it 'Prince', and there are many people who prefer the name 'Archbishop' for the 'cardinal' symbol.
