The Hunt 101 is a must have! I think the Hunt 101 has a nice sharpness and is nice and flexible to write with.
The Hunt 101 and EF Principal are very familiar. Opinions differ on the sharpness of the point. I find that writing is more comfortable with the Hunt 101, but I also read other opinions that the Hunt 101 scratches a bit more.
