The main problem with the Abyss was when using it straight out of the Box, everything is so tight, once you have used it a bit everything is very smooth. I have tried every stock coil except the Nord and for me the GTX wins hands down. I have one in both my Abyss and Vape and Flavour is very good. I do seem to have condensation problems but can't think of a way to avoid this, it's not as bad as the BB Though. I have the Vapeshell in my BB and for me the flavour pops and is very nice. I am now hoping that BB Prices come down so i can buy an Authentic one but can't see that happening anytime soon. I am not going to let my Vapeshell/Abyss problem beat me because i think together they will be banging.
