I vape 70% VG DIY juices all the time in my kayfun lite plus V2. Has the same juice Wells.My biggest concern looking at the deck is how well it wicks !!! I mainly use 50/50 or 60/40 mixes in my mtl tanks but occasionally I do use juices with 70/30 mixes. The wicking channels are very small so I'm hoping that they will wick efficiently.
About the only difference between V1 and V2 is that V2 has a little more airflow.
