Yea great idea !!I looked up the juice Stig's uses and it is NicSalts. Inc, here is their webpage- Buy Highest Nicotine Salt Vape Juice Online | High Nicotine E Juice | Salt Eliquid
You can order that same nic salt juice in different strengths. Since you don't have a reaction from that juice, I would stick with it and refill your other pods with it. That may work best for now. Plus save you $'s
