I used to have a pair of Perspex stemmed GBD lumberman, a Virgin and a Premier, but have since parted with them for a new direction.
I still have a Digby Collector 9619. I use it for the odd aromatic. The finish is akin to the GBD Prehistoric blast.
Overall the stummel makes for a fine smoker, but the cookie cutter stem is dreadful.
Eventually I will have a new stem made for it.
While I'm thinking about it..who makes a good stem for a reasonable price?
