I got fpnibs.com's semi-flex nib, and love the softness & snap-back. It's a real delight on my Gama Sneaky. But it railroaded quite easily, even after heat setting. http://i.imgur.com/8exsjPP.jpg I deepened the ink channel and widened the gaps between the fins until the railroading stopped. But now it can bleed thru on Rhodia(!) and I sometimes see a meniscus in the ink I've just written. So, for my next attempt at adjusting an ebonite feed for this nib, I was hoping for some pointers. How do I prevent railroading? ...without making it so wet it nearly drips ink when I hold the pen vertically? (I presume the current feed can't be salvaged, but I have spares)
