My first PenBBS pen was a white 309 piston filler. I liked the nib a lot, a #6 size fine steel nib slightly bent upward, almost like a waverly nib. However, the rest of the pen wasn’t quite to my liking: Too light and with a somewhat cheap overall feeling, especially the piston mechanism. So I ended up selling it after a while.
After watching chrisrap52 repeatedly singing praise of PenBBS, I was keen on giving the brand another try, but I wanted a pen with a bit of heft, as I find it more comfortable to write that way.
