i am still figuring out the VV PS i can tell it's going to take me a long time to figure out. especially because i haven't actually had a chance to sit down and figure it out. i got it and then 2 days later have been traveling ever since, so it's only gotten one or two uses before it's unplugged and moved again.
from what i have discovered, if you crank it to a nice temperature to get vapor and take a hit or two, then crank it up to 15 or 16 volts after the first hit or two it will heat up nicely to a slowly increasing temperature with each hit. allowing me to get the nice lower temp vapors, and then some of the higher temp vapors. i end up with pretty nicely colored weed. then half way on the last hit i crank it back down to the starting temperature and rinse and repeat.
when comparing this to my myrtlezap i again come to the same conclusion. the myrtlezap offered very efficient very consistent very even vaping every time. there was very little variation and very little control you had over the whole process. you could change up the grind of the weed and the dryness of the weed, you could change the packing of the weed and people talk about draw speed, but honestly no matter how i hit it, and no matter how i packed it (unless i was really doing something crazy) i got essentially the exact same results. the grind and dryness make a big difference, but they make the same big difference with both vapes, so in comparing doesn't matter. with the new CRZ and VV PS you have much more control over how it is vaped, which means you can vape it exactly how you want it, if you know the vape well enough. however if you don't know the vape well enough (which at this point i don't) then you can also get a more inconsistent and less even vaping experience.
so old MZ with standard PS offered very consistent results and very little variability.
new CRZ with VV PS offers much more control over how you would like to vape it and also has a much longer learning curve.
I got very lucky with my old MZ and it happened to vape my weed perfectly exactly how i like it, and because of the consistency i always got perfectly vaped weed.
for me personally i also had managed to over the years find things that worked perfectly with the old brass stems. and the change from brass to SS was small, but large enough that everything that used to fit perfectly with my brass stems are now just slightly too small to be used seemlessly with the new SS stems. this is just a small and personal issue i have, but still an inconvenience for me. so currently if i had to choose a vaporizer to use it would probably be my old MZ, but in time i may come to prefer my CRZ. once i have mastered the VV PS, and have found new things that fit perfectly with the stems.
i still want to get a while to just sit down with this thing figure it out, take some pictures and provide a real solid review of this thing, because at this point my thoughts and opinions are still fluctuating a lot.
