Judging by that color of the rosin , it may work better than a lower temp pressed rosin because it is a little more fluid when it gets heated. Rosin with a light color that is more stable I could imagine being stuck in the cartridge because it is less fluid and may require more "terps" or whatever it is you add
PG and VG are iffy I personally don't like inhaling it because i'm not sure if it's safe and terps sound like a better alternative

Just don't use PG or VG, or vitamin E for that matter, they all screw up your lungs. The macrophages get all clogged up with fat from your lungs, because the juice dissolves it, being an alcohol. It's just a real bad idea. I wouldn't even use terps either. Turpentine is pure pinene, trust me it wouldn't be wise to smoke turpentine. The terps may not be to harmful in low concentration, like in bud, but people are talking about mixing rosin with pure terps, like swimming in it, that's insane.

People have been vaping PG and VG-based nicotine for over a decade, with no indications that it screws up your lungs. They've done studies on first-hand, second-hand, and third-hand vapor from these devices, and there's been no link to toxins, tar, or 'fat clogging up your lungs'. It's worse than breathing fresh air, but there's been no evidence that I"m aware of that PG and VG screw up your lungs.
Whatever happened with the THC carts a little while ago was novel and most likely had to do with a combination of VitE Acetate and mold/pesticides from DIY-er wholesale vape cart guys who make a career out of it. Nothing wrong with making money in this industry, but doing so without knowing what you're doing to other people's health is obviously shitty.

Ok I stand corrected. I've just finished giving your notion a good amount of research time @BobCajun , and there's some validity to it. I was able to find an unbiased study (https://www.jci.org/articles/view/128531) that indicated a disruption in macrohage activity with chronic exposure to VG/PG vapor. It doesn't dissolve the layer, as you said, but rather adheres to it. This slows down the lipid layer's ability to respond to infection and immune response as quickly and as potently.
It's worth noting that to get these results, mice were subjected to 24/7 vapor exposure. The earliest they began seeing a decrease in macrophage function while being exposed to the vapor 24/7 was 2 weeks. There haven't been any follow up studies on intermittent vaping, nor did I read anything in that study about how long it takes after you stop vaping to return to normal functioning.
I would agree with you that we should avoid PG/VG after learning this, but only in chronic users, like nicotine vapers. If you use a THC cart a few days a week for 5 minutes at a time, you will not experience what the mice experienced in the study, as your use time and frequency is a fraction of what it was in the study. 24/7 for 2 weeks vs. 5 minutes every 24 or 48 hours (depending on how one vapes). The concern for me is my friends who vape for nicotine uptake, not for THC uptake. These friends vape pretty consistently throughout the day. Not 24/7 obviously, but enough that it poses a risk imo. The study did note, however, that there was no inflammation, tar buildup, or cytokine response to PG/VG vapor, meaning it's less harmful in this regard than tobacco combustion. I guess people just need to make their own informed choices. Thanks for pointing out something I didn't know man.

It's especially unwise to vape during a COVID epidemic, since it impairs the macrophages. Fat did get into the macrophages, however it got there. I just theorized that it dissolved it out of lung tissue, because where else would it come from? Here's a quote from one page about lung damage.
Just seems like a bad idea to inhale VG or PG vapor when it's only being done for convenience. Of course smoking anything is going to negatively effect the lungs. If you watch somebody vaping, when they blow it out you can see it's a huge amount of VG/PG vapor. It's not like a miniscule amount, it's a lot.
