Hi there, after 3 years on Alan's wait list, he has just emailed me with availability of a few female end GTR units available. They are reasonably priced, however I have bought an Ed's TNT log as well as an Underdog log (18mm connection) and have been using them for 2 years now with great results. Do I really need the GTR since I already own 2 great log vapes?
I received mine recently, they're both 18mm female, one glass, one steel. They join a Couch Log, 2 Woodscents, an Alphadog and a MUSA. I'm still getting to know them but they are very different from the others. I'd rank them with the CouchLog and Alpha in terms of power--they're up there (MUSA's powerful too). What's unique is the open draw, there's minimal resistance.
I got them because they were intended to be powerful (they are!), they would fit much of my gear, and because I'd seen Alan's work and had to have a bit for my own. They glass core I got to have a kind of pure pathway and the steel for durability, to take on vacation, hook up to a battery camping, etc. They're pretty different from each other in terms of power settings and even how they interface with some stems.
The advantages for me are: power, beauty & build, durability and purity, great prices, and mostly, they interface with 18mm male joints and wood or glass RBT style stems. Alan's stems--I have the newer modular ones--are of course the best. He also sent me a paper tube WPA with a cork handle and that's superb as well. I use the others mostly just to fit different pipes and to reduce load size a little easier.
Also, if I purchased the 18mm female ss, what tube or bowl do I need, I'm need feedback from other GTR users. Thanks!
From Alan, I'd definitely look into the modular ones, they are so good. Also ask about some paper options--it's a really neat idea well-realized.
