There is something in life called the 'law of diminishing returns'. This applies to many things, including
vaping. What it means is, there is a point where effect/improvement PEAKS, and you start to get diminishing returns in terms of profit, or in THIS case, better vapor, per effort spent.
In other words, yes, making a GOOD coil improves the quality of vapor in HUGE ways. However, when it comes to clapton
coils, or all the fancy coils, they might have some improvement...but they aren't worth it for the vapor who is simply trying to get the best vape for themselves. When you get into making advanced coils, you leave the realm of practicality and enter the realm of hobby/sport.
