By the way guys 2 x 0.9mm airflow is equivalent to 1.25mm. I have a Fev by SXK with the same airflow and it’s good. This one look exactly like a Fev, just lighter.
It just doesn't work that way...the only thing equivalent to a 1.25 FEV is a 1.25 FEV. Different atties have different structure and airflow path, though it may be "close enough", but the numbers say 1.8mm, which will probably be different enough to the kind of people that worry about such things!
