I've tried both coils and they are both good. I have not tried the "new" BVC coils with organic cotton (as opposed to the ceramic wick ones from before), but I liked the old ones just fine. The BVC has a more 'smooth' vape to me while the GS packs a little more punch. But with the GS coils, you will not have to change the metal pin on the bottom.
Btw, my possessed Egrip magically started working again. I don't know what changed. It goes from working to not working randomly. Usually when it works, it works for a long time before it randomly stops working in the middle of me vaping. I drew air slowly through the USB port for a little bit... yea I was out of options, I was trying everything to get it to work lol. Maybe it likes having air sucked out of it from the charge port. When its working, the Egrip gives me a solid vape. I also have leaking problems with it though, it's pretty annoying when I have it in my purse and I know its just soaking into my purse lining.
