It is really hard to put a finger on what atty will be best for flavor.
Because, flavor is subjective. and Flavor changes from day to day.
this is all based on tongue receptors, juice, build, power level and airflow, probably some other things I am not thinking of right now.
Vapors Tongue can cause muted or no flavor. Eat something with a completely different and strong flavor profile.
Or, chomp on some jalapenos. Brush teeth and try Listerine. You might see that flavor come raging back.
I was loving the TFv4 and it is still a good Tank, but today the Velocity is my go to.
I have the MutationX v3 and I like that atty, I also have a Tug Boat, think it is a v1 Clone.
I like that one too on some days.
I have a Magma, Mephisto (Authentic), Tohb and couple others.
These are all good flavor chasers.
While the atty can play a part in flavor. The build and other factors I mentioned do as much if not more.
Every atty mentioned has a sweet spot for different reasons and different people.
It's hard to say what will work best for any one individual.
Lowering or raising coils off the deck and position to air holes can also play a factor.
It truly is a personal adventure for each individual. And, some atty's work better for some people than others.
BTW, all the other atty's I mentioned I have not touched since I got the Velocity.
If someone insisted I give them a recommendation. That would be the one. Velocity.
One of the best clones I have picked up and would buy again if I lost them.
