I used to drip my Bobas on my VVN (2-3 drops) before getting my phoenixRBA, but on the go I prefer using my Kanger T3 for my high VG based eliquid. I reserve my VVN for my high PG based daily vape (63%PG,27%VG,10%PGA). Even with my cotton wick on my VVN, it's doesn't wick high VG based eliquid fast enough to keep up with my chain vape (even with tip and twist).
