The best I could do with a quick look through my vendor list was Vapor Alley
Vision who offers the genuine Vision Victory tank that is suppose to be an updated version of the vivi nova as well as the T2 that appears to be longe wicked from the picture as well as T2 replacement heads that definitely show as long wicked.
Since you have a variable volt device, the ohm rating is not as important for cranking up the heat. The thing is, you can only go so warm until you start to burn. The T2 has the coil as close to you mouth as you can get thus the warmest vape for any given wattage. The vivi is a mid coil and is not as warm.
EDIT: I did not dig deep enough in to Vapor Alley. If you type Vivi Nova in to their search you will find many more Vivi options. Don't forget one or two
510-ego connectors and maybe a small beauty ring.
