There are lots of juice vendors that let you specify the exact mix as far as VG and PG. Some will even offer totally PG free juice (no PG based flavors) for those that have a bad reaction to PG. There are really too many to mention them all easily. You may need to get into the details of the juice ordering process to see what they offer. Some will also offer different throat hit levels, Viking Vapor comes to mind, but I'm sure there are others.
