Yeah that's the thing, every juice is different. With Red Pill, the menthol is very strong so I drop to 10-15w.
You need to find your sweet spot, it doesn't matter as long as you're happy with the flavour that suits your tastes.
Fully understand and agree with you but by no means am I a new vaper (going for 4 yrs now) so I'm well aware of sweet spots, wattage settings, etc but eish this tank has me baffled but like I said let me shove in a new coil high up as Rainstorm suggested and lets take it from there lol
