I was a light smoker like you and was concerned about the strength or liquid... I have found that 16mg is perfect for me. May have been a little stronger than I was used to but was just right on...
I have the pcc with the 510 and the pcc is taller than a pack of analogs but thinner... quite easy to carry..
I do have a bottle of Vapor Talk Grape Soda...but have not tried it.... I cannot seem to put the Traditional tobacco and the Dulsis down..
My faves are the TT and the dulsis... Both are great tobacco flavors....dulsis has a sweeter taste kinda like a hint of caramel...
Oh BTW Grape soda smells awesome....just like a grape nehi
