I hear you.I feel the same way actually. For a little while I thought I liked a fine nib the best, but once I bought the Italix Churchman's Prescriptor with an italic nib I fell in love with the flow and the nuanced line variations it makes. I actually enjoy that slight bit of flare it makes as I write.
The only things I don't like about this Italix is that there is a huge step down from the barrel to the section that I could do without. As much as I love the nib, it is a hard starter and takes a couple of sentences before the flow and smoothness really kick in. But once it does it's great to write with and I don't want to stop.
I am looking around for other pens that offer an italic or oblique nib and Lamy seems to offer some so I am looking at those right now.
Lamy makes wonderful pens.
For the past several decades I have tried many brands, but nothing came close to Montblanc (with medium nib).
So, this hobby of mine is dying as I settled with Montblanc for good.
