Standard resistance (SR) attys and cartos provide a cooler vape, while Low resistance (LR) attys and cartos, which most people prefer, provide a warmer vape with more TH.
Standard resistance is generally considered around 2.5-3.0ohms.
Low resistance is generally considered 2.0ohm and below.
What PV do you use? While most people prefer using LRs over SRs, not all PVs can use low resistance attys/cartos.
Slim ecigs can only use SR attys and cartos, and they are not made to handle The extra draw of power that an LR requires.
Only bigger battery PVs can use low resistance attys and cartos
