Actually that does sufficiently answer my question. The way I was interpreting the info given on their site, I was thinking they abandoned the 100% VG formula in order to achieve more flavor with PG. More flavoring added to the VG makes perfect sense. Most times I order AV juice from secondary vendors when I need to purchase hardware, and I was comparing a non bumped bottle with a bumped bottle from directly from AV. The bumped bottle seemed much thinner, so I think I prefer non bumped.
