Thanks for the help peglegThat's a great help I shall try that out, hear so many things about keeping the coils high above the airflow and keep the gap between the coils as close as possible, but I shall make some new coils tomoz, maybe try a new build.. Maybe 40awg kanthel wrap around 26 core ni80, see what the outcome is... yea I've had a fake avocado didn't realise!! Typical eBay wrip off and iv used the smok beast rdta, which proved tricky building on but was ok
