I don't know much about airflow dynamics myself, although, being a mechanic, I can say this:
A narrower drip tip can't produce a more restricted draw. Feeling like it does is a placebo effect. Your mind wants it to be tighter, so it feels tighter. Which is fine. If it feels tighter, then keep using that drip tip.
The reason it can't be, is that the amount of INTAKE hasn't been changed.
In terms of a car/engine, the drip tip is the exhaust pipe.
Unless you restrict the source of air intake, the restriction of the exhaust can't reduce the amount of air taken in. All it can do is slow down how fast it goes out.
The hot rods with loud exhaust pipes? They've got wide open pipes, which gets the exhaust out of the engine in a hurry, thus more sound. But the amount of air being fed into and
through the engine has not, and cannot change, unless the intake itself is changed.
Another way to look at it is:
A balloon filled with water. Poke it with a needle, and a tiny stream shoots out. The balloon will drain slowly.
Slash the ballon with a knife, and the water will drain very quickly.
Either way, the same amount of water will come out of the balloon, but at different speeds.
Or we could use crowd control:
A crowded theater, with every seat full.
They all entered through the front, which has multiple sets of double doors.
Smoke alarm goes off, and only one rear exit door opens. The crowd takes a long time to get out, because the one door is small.
Same theater, same head count, smoke alarm goes off, this time three rear exit doors open.
Crowd exits three times faster.
The doors are the drip tips. They can't change how many people came in, or how many people are leaving. They can only control how fast they leave.
The people are the air. The same amount of air was in play for both scenarios.

But again, I've never studied aerodynamics, airflow pattern dynamics, and I'm not 100% sure if those are even the same thing or not! Hahahaha!
Just some musings from a wrench-turnin' redneck!
