Everyone, thanks for all the wonderful responses.
Pravda, now that I have gone through this experience, I would recommend getting a nib that would really leverage the expertise of Montblanc exactly where the sweet spot it. They offer quite a few more unique nibs that are not part of their nib exchange. Such as an ultra fine, a flexible nib, a signature nib that looks very similar to my nib, and also nibs for non English calligraphy. In all honesty, the Japanese such as Sailor own the super and ultra fine category so don't really bother with those. I also would not bother with the flex nib because it's really more of a bouncy nib than a flex. The only ones I will whole heartedly recommend are the super extra wide calligraphy and signature nibs. Those are unique to Montblanc and you really can't get it from any one else.
Dcharles, I personally have not seen a Montblanc music nib so I don't know how different or similar it is. I have many other music nibs including those by the big 3 Japanese pen makers, the Franklin Christoph and even an old Waterman music nib. Japanese music nibs are pretty much stub nibs, the FC nib is really a 1.9 calligraphy nib, and the old Waterman a flexy italic nib. This is a very stiff nib designed for calligraphy. The way Axel described it was that this nib is designed to deliver ink consistently across the entire width of the nib with clean edges. He told me that was not an easy design brief to deliver to.
Here is a picture of it compared to other wide nibs I own. The Pilot Parallel 2.4 and the Franklin Christoph 1.9 Music. There is also small cursive at the bottom of the page. That was written with the corner of the nib.
It truly is a privilege to own this grail pen/ nib, and I am happy to be able to share the experience with you all.
