Device - freebase throat hit

[Musing]

Hi

I am looking at trying freebase nic as it is easier to mix without dealing with the flavour dilution - when mixed : rather than salts.

Can someone help me out about what concentration of freebase I should be looking at and what device would be best to try this out on.

For context I am using 2 Caliburn pod devices and use a nic salts concentration of 30/35mg.

Any advice would be great.

Thanks
