I would stay most people stick with SR. I use standard resistance on twists because they work better at a higher voltage and there is less risk of getting a burnt taste. I only use low resistance things - specifically cartomizers on 3.7v
devices like 510
batteries and standard egos.
LR or low resistance (~2 ohm) and requires more power, but creates more heat and vapour. Standard resistance (~2.5-3.0 ohm) uses a bit less power, but has less heat and vapour. However if you're using variable voltage, I believe SR has a slightly better range that it works well at, plus seems to work better on higher voltages. Someone else can explain ohms in detail or correct me if I'm wrong.
The new Stardust 2.0 comes with replaceable heads, so you could get a higher and lower ohm to try out, cheaper than replacing the whole stardust. I believe they're ~$3.
