I've just bought the Rose Cyclamen and I love it to bits! It's in my Parker 51 Signet with the broad nib and gosh, it's fun.
I want to get the R+K Solferino and Fernambuk, but it seems to be difficult getting it in France.
Me, too! Rose Cyclamen is a new favorite, as is R & K Solferino. Really rich colors and worth the extra effort to get them! And I cannot recommend highly enough Pelikan Edelstein Turmaline. The shading is tremendous and there's even a bit of subtle sheen on the right paper.
