Not to focus on the past, but I am curious as I am little late to the Aspire bandwagon. Why were the BDC coils deemed not that good? The BVC coils have been coined as "far superior", so I wonder what were the faults with the BDC coils.
I do notice they seem to produce a warmer vapor and are harder to draw from so I use a lower voltage to avoid burning them.
I have the new Aspire Nautilas Mini and so far it is great!!! I also have 10 coils of the BDC remaining that I am also using (another reason for my question) so if there are ways to prolong their life I am interested in that as well.
