Some people like shaking the crap out of the bottle back and forth while at the same time strengthening their masturbation hand. Two birds and all that

My wife has a SEVERE sensitivity to PG, (causes vascular cluster migraines) to the point where I can't have any PG at all in my liquid. All of our liquids for our vapes are PG free for this reason.

I use VG nic to keep my ratios up around 80/20. I'm on RDAs so I need it as thick as possible.

Only reason I can think of is they want an all vg mix. I made the mistake ONCE.

Most flavors are PG based. If you're trying to blend an 80/20 or max VG blend, it helps keep PG to a minimum.

I like max VG. If I add even a little PG it hits too harsh for my liking and there's less vapor, it's less satisfying to me. Just a matter of opinion.

For the nic I just grin and bear it, yeah it takes a while with a syringe but oh well. For the plain VG I put the bottle in a hot water bath for a while, then pour it into my bottles with a funnel, easy as cake.

Some people might want to limit their exposure to PG as much as possible, maybe due to an allergy whether real or imagined.

I like to buy my nic bases in sub-lethal concentrations. The only way I could use PG nic base would be for it to be <= 10% of my mix since I am already adding 10-20% in flavorings. I vape at 9 mg so that would means PG base nic strengths of around 100 mg/ml. Yeah no thanks. 70/30 is my target split.

I use a high ratio because it stops leaks on my rdta and it doesn’t spit back anymore so now my lips are burn free and my hands are clean

When I started mixing 3 years ago I used VG-based nicotine so I'm just used to it at this point. Plus I have like 1.5 liters in the freezer so it'll be a long time before I need to get more.

Your edit got it. PG Sensitivities. I still tend to get the PG based anyway because the VG seems to oxidize easier/quicker and the hotspots are harder to work out of the VG based.

I just chose it at random and got used to it. I put mine in a unicorn bottle so I don't have to fuck around with syringes and oxidize my big jug every time I mix.

Honestly, I hate the taste of PG. Also, any harshness in my mixes is hell on my throat, and I'm a singer, so that's no bueno.

Max vg cloud lyfe /s

I use max vg because 1) rdta 2) its just easier. Nobody sells pg around me but I can stroll into any store and grab vg if I run out.

You get less of a throat hit with vg nic and also i mix pretty much 80/20 for everything so I need the room for flavoring.

I order %100 VG based nicotine, and depending on the end ratio I might cut it down with PG to a 50/50 ratio. Most of the liquid I mix is at %80 or higher VG, and PG based nicotine makes it impossible for me to get high VG in some of my recipes. As with anything VG based, temperature matters, I do long term storage in freezer, mid term in fridge, and room temp for shaking, mixing, or adjusting ratios. Lastly, if your arms are tired, you need powertools, I got one with a flat ribber grip plate, lets me use lots of different sized bottles, I picked up mine reconditioned on eBay.

I keep a 60 ml bottle for mixing. I top it off from my big bottle. I just put the 60 in warm water before mixing. Easy to measure with pipette after that. I like to make high vg mixes. I only use pg in flavors. I vape on an rda.

According to the research done by Dr. Kurtz it degrades much more slowly in vg than pg.
