You’re very welcome 
The Boost 3 is almost good, their atomizers/coils are also “good” (0.2, 0.3, 0.4ohm), it doesn’t leak at all 
, I’m not happy with the drip tip 
, I just bought an acrylic tube on AliExpress 15mmØ x10cm
I’ll cut it to size, drill it, I just don’t know how to hollow out the space for the rubber gasket from the inside yet 
. I think the Soul would be very tight DL for me, I’ve been considering it, and the Soul 2,

but then I let it go because the “atomizers” start at 0.6ohm.
Still, thank you for your help and recommendation
