GH Rum Flake from 2004 in a Castello Old Antiquari 15 KK, this baccy has a bit too much of the Lakeland flavor for me, but I do like the slightly sweet flavor that it develops
Probably need more than a dab. I coated the tenon of my problem pipes with this stuff. Your Vauen takes 9mm filters right? PM me your address and I'll send you some.
I've read to always remove and put on turning clockwise, if that helps.
Also I've used a dry lubricant on stems that get stuck. I'll have to check what it is when I'm back in the office.
