Vaporesso NRG, NRG PE and NRG S (not NRG SE) tanks

Use the Ijoy EXO-S RBA to make these more of a flavorful tank than a cloudsbro tank.

If using higher VG juices (65 VG or higher). Grind down 2 spots on the lip of the base of the tank (the lip that's sits around the RBA) where the juice ports are on the RBA and now the juice can flow better to the juice ports. That lip is so close to the RBA that it almost obstructs the juice ports on the RBA completely.
This is not needed for thinner juice.
