Agree that flavor intensity in the Hadaly is influenced by it's air flow, same as all atty's are, but that's not the only factor. The atty's fluid dynamics, the build for the particular joose ran in any atty, your vaping style also influences the flavor you get. To me it's not less vapor in a Hadaly, I can chuck clouds in mine with the builds in them, but rather that the vapor is more dense and flavor saturated because it's fluid dynamics are spot on. The Hadaly is not a big air atty, so I go all the way to the wild side, run them with "wide open" air and build for the joose ran in them.
My goal is to try to do the same in all of my atty's. With the big air atty's especially I stop down the air flow to a balance between what is not a too restrictive draw for me and achieving what is the best flavor rich vapor I can get from each of them. With some atty's/liquids that may also require altering the build to compensate for less air. Splitting hairs maybe, but it's all about flavor to me. Achieving that is not rocket science when you know what your DIY's (or premades) want as well as I know mine,,and learn how to get that from an atty that is capable of delivering it. To borrow the great term "optimize" that @Silver related to me, I optimize all the variables.
I have a Petri V2 that I like as well. But by design I can not change the air intake without changing my draw that I don't want to do. So I am only left with altering it's fluid dynamics some with coil placement and air intake orientation. The Hadaly ran as it was designed to be ran and built to the joose ran in it doesn't need any voodoo magic tricks to make it stellar for my uses. I have a lot of 22mm atty's, and none of them are as easy to get what I want from my DIY's that I prefer single builds for as in the Hadaly. I'm hoping the Kryten will be the same for my DIY's that I prefer dual builds for.
@Spydro do you find the same as i do?
I find single coils work beautiful for menthol, tobacco and fruity flavours.
While dual coils always bring out the best flavours in desert and bakery flavours.
