New Cherrywood SS female GTR with maple roasting tube, clear glass tube and wpa. The wood roasting tube is in two pieces - the long tapered end of the tube fits in the short end roasting chamber; I ordered a glass tube to line the long end of the roasting tube and you can also use a paper liner, and a paper liner is inside the roasting chamber up to where the screen sits. You can get a colored glass tube from Alan but I prefer clear glass. You do not necessarily need Alan's wpa, both my Underdog and Arizer solo wpas work just as well, and the Arizer wpa is easier to pull out. I would like to find a wpa with a glass screen that would work and if anyone knows on any, please let me know. Be careful using 18mm male pieces into the female GTR, they will get stuck.
I have been using the GTR exclusively for the last 2 weeks, and also own an Underdog Alpha and Woodscents. So far, the GTR has the most unrestricted airflow while delivering excellent vapor, at least as powerful as the Woodscents, and more powerful than the UD. A lot of versatility with this log as a lot of different tubes/adapters will work; I have used an Arizer solo bent stem with a glass screen (put an o-ring around to basket end to keep in place in the log), several of my UD tubes work, and still experimenting with other stems/adapters. I have been using Alan's glass tube and the Arizer solo tube for micro-dosing, and the wood roasting tube for sessions - the hits are great no matter the load size. The GTR works well with a water piece, however I have been enjoying dry vaping more with the GTR - no matter which tube, the vapor is smooth, tasty, thick, and rarely makes me cough.
I am still playing with different watt settings, and depending on the degree to which I want to get medicated, have been setting the watts between 10.5 - 11.3. I have not had to wait nor have experienced any degradation of temp or vape quality after doing 5-6 hits back to back. This is built with Heat Island technology and can be left on 24/7, although I turn mine off overnight.
I was hesitant to add another log to my small collection and soooooo glad I did - Alan makes top notch products!
Cheers and happy roasting!
