What some consider "great" others may not.
Agreed, and your build won't work for me. It is great that after so many failed attempts you found something your happy with.
because you had such difficulty in hitting the sweet spot for how and what you vape does not mean others will, or do.
Way to many variables for a one build fits all scenario. That said the Kayfun Mini 3 is one of the most forgiving tanks I've built, you can do a mediocre build and it still does pretty well.
If someone is able to put pretty much any build in an atomizer and end up with great results it probably means they are an experienced enough builder that they are able to achieve proper wicking regardless of the coil used. It certainly does not mean they are "full of bologna".
The diversity of builds the mini 3 works great with attests to this fact.
When someone posts a build on the forums it is not, or shouldn't, be considered the "sliced bread" of vaping, it should be considered a starting point for less experienced individuals, or just a simple guide.
Airflow, power, wire type, wicking media, coil location/proportions, even flavors used, all play a part. Once you get down to it most everything is subjective.
