I'm new to
vaping, so my experience has been limited to the menthol and cherry Blu cartomizers, which I believe are 100% PG. Neither of these has been very satisfying to me, so today I ordered a Riva 510 with a mix of flavors to include 100% VG, a 50PG/50VG, and a couple of 80P/20VG. I'm looking forward to seeing which mixture I prefer.
