I have recently got into RTA tanks. Mostly because our Canadian government has become semi ant-vaping. I used mainly Aspire Nautilus coils and tanks but nearly all tanks are illegal to sell now. Seeing what was coming, I bought whatever rebuildable tanks that were left in the market. I figure drop in coils maybe a problem to buy in the future. Most of the RTAs were duds to me as I like to vape a very loose MTL style rarely over 20 watts. The Merlin Mini suits me well as I like tanks that have good air flow options. One issue I find is that the cotton sometimes lifts out of the juice well causing a minor leak. Am I doing something wrong when wicking? I use a 28 gauge kanthal round wire with a 2.5 mm diameter coil at 1.5 ohms. Also any suggestions on other tanks as I can still order from China. Was looking to pickup the Brunhilde MTL but I don’t think I will like the airflow.
