Single coil vs Dual coil tanks

[Dexter]

Hey guys. I started out with a vtc-mini and Kangertech mini tank, using the rba, which served their purpose, but as always I wanted more out of my setup. Enter the Mini Goblin... Amazing tank, flavor like no other, and clouds for days!
Next came an rx200, which my Goblin liked to call home. My adv was the Kangertech, while the goblin was mainly for home.
I then purchased an Aromamizer - best tank ever!
Since then the builds have gotten lower, the wattages higher, and the Kangertech has been collecting dust..
Here is my dilemma; since vaping on the Aromamizer I have developed a tickle in my throat and a bit of a vapers cough - it sucks balls!
I Vape 3mg, mostly DIY, dessert flavors, and have never had a problem like this before using the bigger tank..

Most welcome to the forum.

A difficult one. What ration VG/PG are you doing? Have you tried going higher builds and lower wattages again to see that helps? Have you changed to a different flavour concentrate recently?

No changes in my concentrates or nic. 80vg 20pg, as always.. I have been using lower builds on both tanks - between 0,2 and 0,3 ohms, running between 45 and 65 watts..
I used to puff my Kangertech all day and had no issues at all. It was at about 0.5ohms and at 24,5 watts though.. I'm enjoining the increased flavour so I don't really want to build higher, although I have put a 0,35ohm build into the Goblin to see if that helps..

I am stumped. Maybe try less VG - it is known to cause some lung irritation in the longer term for some. And make sure you drink enough water.

I've definitely upped my water intake since I've started vaping. I find that increasing the pg gives me too much throat hit, which I'm not a fan of.
A possible reason is that I am vaping at a higher concentration now than on the single coil, and it tastes so damn good that sometimes forget to stop!
