Don't worry about asking questions, we all went through a learning curve. That why the forum is here!
Word, Chefdeuce! Never be afraid to ask a stupid question...there are none, especially in the New Members Forum. We all entered this world knowing nothing and making lots of mistakes along the way. Its called learning, and learning without is FUN!!
I use VG juices, no PG. They are thicker, and so I thin with about 20% distilled water. PG is too drying and scratchy to my system. VG is smoother and sweeter. I have no issues with throat hit at all. Its plenty good enough for me, and no issues with nic. For me vapor quality depends as much on the cart material and wicking ability as the juice itself. Thinning VG juices is necessary. Distilled water or 10% alcohol (like PGA or vodka) work very well for this.
And the VG the OP showed should be fine. Lots use that one here with good results. It should say USP on it though. I use Heritage VG from Whole Foods with good results.
Vape on!
