Flavor and vapor production are quite the balancing act. It has a lot to do with coil placement, coil style, juice blend, resistance of the coil, air flow volume, air flow direction on the coil, etc...
The ideal vape is going to be different for everybody.
My ideal vape is huge flavor with good vapor production. Typically a 1/16" micro coil positioned right in front of my air hole (as close to the hole as possible) with the air hitting dead center on the coil. I use about .8ohm on my mechs, and around 2.5-3ohms on my VV so I can crank it up. My air holes range from single 1/32" to 1/16".
Basically, you want to find the happy spot where your air cools the coil to the point where your vape has the correct flavor, temperature, and vapor production that you want. That is going to be huge flavor, huge clouds (wide open air and lung hits), or a happy medium.
I wish there was a simple answer, but what it all boils down to is a whole lot of coil building to find what you enjoy.
