Smoother is subjective. A tight draw feels more like a cigarette, while a loose draw feels airy. In hot weather, a loose draw can actually feel harsher because you're pulling in more vapor at once. Starting with a tighter setting can give you a smoother, more controlled pull. You can always open it up after a few puffs if it feels too restricted.

It's about finding the balance that works for you, not about following a rule.
