Been using mine for about 2 weeks now, 100% my preference is 0.8 coil.
I have tried the 0.3 and 1.2, very disappointed with the 1.2 tbh (luckily i only purchased it as a single from ubervape), i used it with nic salts and the flavour was just about ok, if i compare that to the artery pal 1.0 coil its no where near but i also understand there is more AF with the Vinci.
@AJT how u finding the 1.2 now? i see u tried that one too.
The 0.3 is good, nice flavour and cloud but big clouds are not my thing so rarely use this coil.
The 0.8 is very good, i change the airflow occasionally but there isn't much difference, its more of a restricted DTL which i like. I've used both nic salts and 70/30 but i prefer using a lower nic salt around 10 or 12mg. Decent vape.
I too get some leaking more from the 0.3, tried all the tips in the thread but it does occasionally leak, at night i take the pod off and place it on a bit of kitchen roll.
