Alyssa, my Lamy 2000 has a nib the is a little less flexible than my 3V, but more flexible than an other pen I have tried. With light pressure, the tines spread, and when you release, the tines spring back together. Apparently, the 14K gold alloy is very-very springy and allows such respring memory.
Nice, I now use her for Copperplate practise. It feels just like my 3V.
