HeavenGifts have a largish supply of 2.1ohm vapeonly BVC coils. These coils were interchangeable with all the aspire gear and I used their coils in my BB. I have just take delivery of some and with fingers crossed opened them up. Yippee they are the old style BVC coils. Ordered some more and I am now set for ages. Phew.
