Odd as I have 2 V3 and only use the original Aspire BDC and they are my favorite Ego combo devices
(draw on PT Mini 2 is better, but I like the aspire flavor better)
While I mainly drip and use mechs as well as use my KFL and Nano on my Vamo( normally at 14 W), I find that the Aspire BDC and V3 coil combo still works quite well
Now as far as the aspire coil quality, there was a thread some time ago discussing Aspire being aware of the Coil issues as I was averaging 3/5 or 4/5 good coils per pack - and there bad coils can be quite ransid!
Now that they have moved onto their flagship Nautilus and Naught Mini with their new BVC, those seem to be the class of their product line, and where their focus will be on.
Agree you have to use a fairly hard draw on the BDC tanks, but the flavor has always been quite good for me
Usually run their 1.8 coil at 4.2 on the V3
(just tried one that I had not used for 3 weeks and it is working fine - kind of nice for a change after using the CLT on fully open draw for the past few days !)
