JP,
It really depends on what you like to write with and the size of your hands.
Got kind of big hands and hate writing with its-bitsy little POS pens. The el Grande, Churchhill, Gentlemans, El toro and El Presidente fit me REAL good. The Baron nib holder is too small in diameter to be comfortable for me. This goes for all the junior pens and American derivatives.
So, for last major pen swamp, made a real sweet el Presidente and the recipicant says it's a desk pen, too big to fit into his shirt pocket. (It fits into thee front shirt pocket of my xl & xxl shirt.)
SOOOOOOooo, different folks, different pens.
Look at them, figure out what you would probably like, and go try a couple of them.
