I have taken my recently purchased D10 and shipped it off to Pendemonium for a nib regrind to a cursive italic. The nib was buttery smooth, but so perfectly round that I couldn't really feel that I was writing with a fountain pen...if that makes any sense. This way I can feel the line variation and give my words some, well, character.
Will reply again when I get it back, perhaps with pics.
FWIW, after reading a few posts about it, I tried carefully flossing (sort-of) my Copper Temple with a razor blade - not forcing it through, just gently sliding it through the channel a few times, and it could just be my imagination, but it actually seems to be writing better. I can get it to release ink with a gentle touch to the paper much better now. I suspect the oozing may have been from needing to press a little when I was writing, as that seems to be a lot better now too. Lastly, by getting it to write with a nice light touch, it actually has a fine line now, instead of looking somewhat bold-ish. Perhaps the ink consumption will slow a bit too... Anyhow, much happier with this pen now. Since I didn't force anything, not wanting to spread the tines, it is quite possible that I'm imagining everything and the only difference is how I'm using it, but I'm sure I had been trying to get it to write with a lighter touch, and it deffinitely does write faster now.
