NatureVape DCD Pro Coils Advice

[Birdvapes]

Can't recommend these coils highly enough. They bring so much more life back to my Aerotank 2 in terms of flavour and vapour production, and the fact they're so simple to re wick means despite the high initial price, you save a lot of money However, my own re-wicking varies in flavour consistency greatly, and I struggle to vape past 8 Watts (still a good vape on these but for a 1.4ohm coil I'd expect higher) without burning my wick, what advice do people have for re wicking? Still using the same cotton that came with the coils, and most of my juices are higher in PG than VG
