to be more precise about my new setup :
cuboid upgraded to firmware 3.1 (hardware version 1.01)
2xLG HG2
herakles plus
i'm using the SS316L coils in TC mode using the TCR mode adjusted to 108 (as mentionned by DJlsb in his review of the cuboid)
i'm vaping 80% VG juice from 12 monkeys vapor
my settings are 50W at 220celcius
I really like being safe with the 12 monkeys juice. Those are really hard on coils.
I like the taste (or the absence off) of the stainless steel coils... i have been vaping for a day now with the setup, and it seems that those coils need some time before being at their best.
i hope it helps
