I've been using mostly pg and around 10-20% vg in my juices.. last night I mixed some chocolate.. one using capella's double chocolate and one using TPA milk chocolate.. I used 40%vg on the capella juice and 30% vg on the TPA juice. both taste pretty good but wow! the vapor! I can't believe how much more I get using a bit more vg! especially the mix with the 40%
