Since I have a box of the Aspire 2.1ohm BVC's in my possession I've been wanting to use the coils in my eGrip ever since I found a few videos on Youtube showing how easy it is. But, I've only read and seen egrip users using the 1.6 or 1.8ohm version. I was wondering if anyone in here has tried this out or is currently using them I the eGrip. Pros? Cons?...just wondering
