So I've pretty much switched over to the FVPS after my break-in period. As other (notably VH) have noted, its a natural progression, going to the HI from the MFLB. I agree completely with this. I'm glad I had the VVPS for the period of adjusting to it and all the friggin' combinations and draws/pulls... etc. It really is kind of overwhelming at first. The VVPS kind of gives you that safety buffer, plus lets you get used to the temp, IMO... the HIsaber was made to run.
Alan designed this thing around the 12 vdc and its there (well, 12.24 +/- 3vdc probably) she works best.
My VVPS pretty much sits in the closet, keeping the HIsaber on ready at 10 volts. When I'm ready to go, I grab the OEM PS and let her rip. Plus, I hate lugging the VVPS around.
Easiest thing to. I found, if I just hit HIsaber Sumac, like I was smoking a bowl... we get along fantastically. At least that's been my experience, so far. Oh sticks. It got rid of the Lung Butter to, treating it like that. Screw all those voltage settings. Let someone use them to adjust.
All this time, screwing around, trying/succeeding to vaporize. I should have just acted like the HI was a BIC, without a flame. I might upgrade in the future on the VVPS. But, I can't see it, unless I'm leaving it out 24/7 and that's not going to happen. This is the way, I like a vape to hit. Like I'm smoking a bong. One of the reasons I'm into Glass, is because of those days. A Healthier throw-back to that... HELL YEAH!
P.S. Broke my 14mm ground tube back down, so needed to clean up about a 1/4" of wand hash. Shook it up in Ghost OG, laid down a layer in the tube and Holy Medicated, BATMAN!
