I respectfully disagree. I would put my black locust CRZ up against any other log vape and expect to win. Thick white clouds trickling down into some wispy ones. Averaging a good 5-10 hits per stem. It is a beast. The PD I had couldn't compete. Even my "cooler" running one with the "bluish" vapor outperforms the PD.
The PD had a pretty good performance, My CRZ has out-fucking-standing performance. My opinion, of course.
I think comments about different similar log-style vaporizers being "better" than another are generally inappropriate or off base. In this and most cases, with "better" associated with vapor density (presumed related to dosage delivery), it simply means one model (or a specific vaporizer) inherently runs hotter and/or is slightly more efficient in its dynamic air heating ability. I presume that different model Eterra/PD/CRZ/etc.-class log vaporizers used with variable power supplies could each be set by users to comparable 'sweet spots' and would perform, do the job, including producing dense/visible vapor, the same as each other.
Can anyone propose any reasons why one log vaporizer would be "better" than another (for vapor production), other than inherent operating temperature and heat exchanger efficiency, both parameters that could be balanced (well enough, for all practical purposes) by customizing their power settings?
