Hmmm, you lot have me thinking now, so pardon my ignorance here.
The Sierra that I was using as a day pen has the refill which came with the kit from Timberbits, it has always annoyed me that it has a tendancy to "blob" for want of a better word. Hopefully you know what I mean?
The Omega that I'm now using has a lovely writing action and I'm really happy with it.
So, for the Sierra type pens, which of the Beaufort refills do I need?
