I've been looking at a lot of tanks lately that have the rba coil as an option. I currently have a subtank mini on my kbox and have been using the rba section since I purchased it. Other than the initial occ it came with. I'm really wanting to use it for a TC mod (snow wolf which is in the mail) and have been leaning towards the kayfun v4, kanger subtank plus, smok TFV4. I'm a flavor chaser also and want to use titanium wire. The main reason I'm asking this is not only am I relatively new to vaping. I haven't had the opportunity to mess with a TC mod before. As well as the only things I've ever built on are my rba for my subtank mini and a velocity rda. Which Ive heard are some of the easiest things to build on. So while looking at a lot of these rebuildables. I feel spoiled by what I've been rebuilding with compared to others. Thanks in advance for any suggestion/recommendations.
