I've been running exactly the same build in my DL FL as my DL (V3). Same wick, same
juice, same power settings.
I'm finding that after about 2 days I'm consistently getting an almost burnt flavour from the FL clone. The wicks never come out showing any brown through the coil so it's not dry/burnt hits.
True it's slightly more constricted air with the dual 2.5mm inserts in the FL than the 4mm in the DL (V3) but I'm not sure that explains it. Both are 0.5 Ohm Ni80 fused claptons running at 40W.
Any thoughts? I'm hoping it's nothing to do with the "PEEK" chimney in the SXK clone.
