I switched from boges in
tanks to vivi novas a couple months ago. I'm now finding myself switching back. I've been rebuilding my heads with different cotton materials and sometimes they work awesome and sometimes they don't. The boges work consistently all the time. It gets frustrating wrapping a coil only to get an E1 error or it works great for a few minutes then the error shows. too easy to short out. I'm not done with them by no means... but I'm also not done with cartos in tanks like I thought I might be. I've just been too lazy lately to mess with recoiling.
Sometimes we travel full circle to find our satisfaction. I was just fine with my carto/tanks but jumped on the vvn wagon. Rebuilt coils, different wicks, etc. Just never got the satisfaction or consistent performance that a good carto/tank setup gives me. I realize alot of folks swear by them and that's fine, it's all individual preference.
Now my phoenix rba is a totally different story. After re-wicking with a vertical coil, I love it. Great flavor, vapor and th. I just get weary of refilling it so I use it mainly for taste testing or those times when I just get in the mood to really fog up the room.
As for cartos, I've used ikenvapes 510 platinums and 801 fusions, smoktech 1.7Ω resurrectors and boge 2 and 3Ω. If they wick, give good flavor and don't leak, I'm happy.
