So the arbiter and I took a long time to be friends.
I tried, with no luck, all sorts of coils and coil heights and had at best bleh results.
I got so frustrated that it got dumped unceremoniously in the cupboard until yesterday morning I thought I would give one last go and installed a BVC fused clapton, 0.45ohm, 26w, AWESOME. flavour is on point and airflow is much better. Very glad I gave it one final go!
Thanks again @Rob Fisher
@charln coils for the win! ANd only a pleasure! I was surprised when it didn't work for you in the first place. It's an awesome RTA!
