Sorry about that i used cotton bacon and kanthal claptons i dont remember the sizes but pretty sure it was a 3mm diameter
No apology needed, just trying to get more info for everyone to help with.
Like said above, cotton thickness in the coil looks ok. Although it wouldn't hurt to try slightly less on your next rewick just to change it up.
Sapor being a top flow rda, the coils should sit as close to the top air flow as you can get them without touching the top cap. Those look pretty low compared to the top of the posts but maybe that is as tall as you can place them.
Coil placement makes a huge difference in flavor right along with propper wicking.
It could simply be that your friend is using a better juice or a flavor profile that you like better than yours.
An aggressive coil like that (compared to a basic single wire micro coil) may run exceptionally well in your friends rda if it is an airy cloud chucker but could be over powering your smaller flavor chasing rda. Not sure what rda your friend has with the same build that you enjoyed vaping on.
Process of elimination, figue out what part of your setup is different than your friends. Hopefully you find the answer short of buying the same rda as them.
