VG sucks moisture, so if you're another that goes for high VG due to the fad, just balance more PG into your mix.
Some add more flavouring without understanding that flavours are usually mixed in PG, so they're simply adding more PG as they add more flavour.
And as someone else stated, some add some distilled water (just a drop or two) to their mix, but note that depending on your tank, this might make it a bit runny and might leak.
