This is just ME. YMMV. But Here's my take on it. Pink Champagne, tons of clouds at 65/35. I'm always a little amazed by it. Sticky Buns mixed with Cinnamon Roll, less clouds at 65/35. So I think some of the vapor is also flavor dependent.
VG is your cloud-maker, PG is your throat hit. That said, I vape almost all max VG anymore. I prefer the taste, the feel, just everything. I do drip 90% of the time, so if you're a tank person, or carto person, you'll need to tweak your setups to get the most out of max VG juice.
But yeah, you probably have something there. I imagine the flavorings could affect your vape. I know the coil gunkers seem to not provide quite the same volume of vapor for me.
