I've had my 149 Calligraphy for a couple weeks love and my love of the pen hasn't flagged a bit, I love this nib.
My experience with ink has been interesting, soon as I got the pen home I inked it with Iroshizuku Yu-Yake, but almost immediately cleaned that out because the line put down was too faint when not flexing the nib. Next was Sailor Tokiwa-Matsu, and I was constantly amazed by the complete lack of railroading no matter how hard I pushed the nib. That fill lasted a few days, next up was Aurora Black, a nice line when not flexed, but regular railroading, not too bad, but.... Then I thought I'd give Noodler's Black Swan in English Roses a try, pretty much a repeat of the performance of the Aurora Black.
Now I'm back with the Tokiwa-Matsu and railroading has gone the way of the Dodo.
In my mind I always considered Tokiwa-Matsu a 'wet' ink and only used it in pens with a fine nib, or pens that wrote dry.
Is 'wet' the right word? Maybe 'lubricated' is a better word? Why does this ink flow so well in the 149 that the nib never railroads?
I've got a few other Sailor inks - Rikyu-Cha, Shigure & Soutin - I'll probably give one or more of these a try on the next fill.
I'd be happy to hear from other owners of this pen regarding what ink they're using, and the general performance of the nib.
On a side note, I was in the local MB Boutique today to purchase a bottle of Permanent Black, as the staff knew that I owned a 149 Calligraphy they were pretty quick to warn me against using this ink in the pen, but they couldn't really enumerate why. Anyone have any thoughts?
FYI, I was looking for the permanent black for my 146.
On a side-side note, I got a chance to handle a resin version of the writers edition Homer fountain pen. It's a unusual looking pen, but it kinda grabbed me, and felt good in the hand. If it had been possible to buy it separate from the 3-pen set that they had, I might have jumped. So, I guess I got lucky and didn't overheat my credit card.
