Russian v.s. kayfun airflow question

[Dissonance]

Between the two (Or multiple, with all the versions out there), which one has the most open airflow?

 

[folkphys]

In my experience: Authentic R91 by a mile. Likely the authentic KFL+ (v2) is quite open as well. Machining quality and the proper alignment of air pathways (and openings) make a huge difference in the airiness of a device's draw.

^^^what folkphys said. Ive got the authentic R91 and its WONDERFUL.

I don't own a R91... yet... but plan on getting one soon. I'd imagine the Russian has better airflow due to the separate center pin design so you can adjust it a little more efficiently and line up the air hole with the center pin hole.

Russian 91 airflow is so amazing... smooth as butter and it just feels oh so good.... I mean seriously my KFL + clone of every version airflow sucks compared to it.... probably the authentic too

And honestly I think it all has to do with how the side airflow is designed at the angle it is with a much wider bore it's like a straight shot for the air to move instead of the L shape the system the KFL uses... this AND the very deep juice wells combined

Any recommendations on R91 clones then? The authentic isn't too bad (Like $90-100) but I'd have to save for a few months to be able to afford it... I kinda liked my kayfun but wasn't a huge fan (Fill screw got stripped, I think it's actually the port in the deck that stripped... Stupid since I never screwed it down tight since it was a pain to get out to begin with but w/e), normally used my Aqua over it anyway but Aqua has turned into my mech mod topper and my Vamo is collecting dust... Kinda wanna breathe life into it again

Also, with the russian 91... Is the vapor as hot as with the Kayfuns? I loved the flavor from my KFL clone but the heat + draw were killing me... Since the R91 has more open airflow does that help keep the vape cooler?

Unfortunately none of the R91 clones that I've ever seen have the correct placement and orientation of the air intake. Which I think is quite important thus making them simply sand-blasted KFL's and not worth it.

The vape is just as hot as a KFL. Maybe somewhat cooler on account of the smoother more open draw. For my taste, swapping out the stock drip tip for one with a wider bore has helped quite a bit.
