Diana,
Thanks for the post - it's very helpful! I had read that the Aurora nibs have more 'tooth' than some, so it is nice to hear that they are still pleasant writers.
If they tend to run finer than normal, perhaps I would find a F would be sufficient instead of a EF. But I'm not sure, I am ultra finicky with 'Fine' nibs - I often feel the F nib on my M300 is slightly too thick.

The size sounds pleasing also, as sometimes I think the M300 is a tad too slim for my taste.
Overall - very helpful, thank you!

Now, does anyone have any idea of who may have the best prices on the Aurora's? Nearly everyone stocks them, and the prices vary wildly.
