I use gold liquids high quallity i drop liquids in the coil before use i let it stand for 15 minutes and i do primepuffs... im going to follow your advice. 1 im goin g from 2 airholes to 2.5.. thats a lot of more air.. 2 i stop warming up the coil 0.5 seconds before drawing... i just tried this with cuban sigar.. its not bad althoug some heavy/dark taste notes go away.. strange thing is in the vape store they always warm up the coil before testing a new liquid.. i asked them before if that does kill the coil.. but they say no... but i will try
If you need to warm up the coil, you should consider using higher voltages. Alternatively, you could try temperature control.
