I am new to DIY, but I am a bit of a hardcore coil builder. I have 2 Kanger Sub-Tank Mini's running Staggered-Fused Clapton coil builds. I had to modify the area under the screw to fit the wire into the channel. But the flavor and vapor production is freakin insane. I also have a Goliath running dual Fused Clapton builds. I can tell you that getting RDA flavor from a tank is achievable. But not with standard coils.
I can actually sometimes get better flavor out of my tank builds than I can with some of my Clapton RDA builds. Mainly because I tend to challenge myself more on my tanks to fit crazier builds into them. I use my drippers for testing so I usually opt for a quick coil change. Even a simple Clapton coil in a Kanger or Goliath can achieve some very good flavor.
