Hey all. I got my VCT in today and with it a pack of Ni200 coils. The 0.5 ohm vertical coils (A1) rock, but the first Ni200 coil I tried seems to be very inconsistent with it's vapor production. I've had the rDNA 40 for a couple weeks and it works stellar with my Russian 91 clone (after watching a build video from Kayfunmods I highly suggest using the 6-32 screw to wrap nickel coils). Anyone else have any luck/issues with smok's Ni200 coils?
