I've never had much luck with the W&N ink, but ink is a pretty subjective thing.
You can actually use those 2mm lead holder sharpeners? Wow! All I ever seem to do is continually snap the lead off, haha. I'll give you mine, in case you need a spare
Haha oh i'll take it! If I use the red or blue leads then I also snap them off VERY frequently. I have started using a standard HB lead though, which has been much sturdier and caused less breakage.
