I see posts on the resurrector carto on Vaporescense BFT, but didn't see anything about leaking like I've experienced on the dual coil cartos on the BFT. I also don't like the super hot vapor coming off the dual coils. Are there single coil long cartos (48mm) that would fit on the BFT? I also tried the 3.7 battery on the LR Boges and it's too cool. I guess I need a provari to get in between voltages, unless there is a 5v battery out there that would fit my Bullet.
