This may have been answered already, but is anyone else having wicking issues with the thick single thread version of the wicks that came with many of the 2.8 ohm heads? I have major issues with dry hits on those heads, but no problems on the 1.8 and 2.4 ohm heads with the 4 slender wicks.
Yeah I have the same problem. I used the short wick version for weeks with zero dry hits. Bought a couple v2.5 novas yesterday to use with some long-awaited juice that came in and started getting the dry hits. Actually the 2.4ohm head was giving me some problems as well around 4.2v, but not nearly as bad as the 2.8ohm head which gives horribly burnt hits at anything over 4 unless I tip it up while hitting it. The 2.4 head works wonderfully on my kgo battery though, and I don't get severe dry hits with the 2.8 head but it tastes like crap. This juice is 65/35 but I was using 100% VG with the short wick heads and could easily crank it up to 5V on the 2.8ohm head. So for me the long wicks aren't wicking fast enough at higher voltages.
