Is the draw looser on the nextasis, as I read that the smallest setting is 2 X 0.8holes. A lot bigger than the nextgen and nextiny
This is actually the
smallest possible setting on any VWM atomizer, assuming you're using a single, stacked airhole configuration. Let me see if I can extrapolate and have all this come together...
The smallest pair of airholes on the NextGen is 2 x 0.9mm assuming you're using the single-slot AFC ring (obviously there are dual and quad-slot rings as well), ,then moving upwards to 2 x 1.1mm, 2 x 1.3mm and finally 2x 1.5mm. The stock Nextiny obviously comes with only a single-slot ring, allowing for exposure of two holes at any given times. The smallest set of stacked airholes is 2 x 1.0mm, moving upwards to 2 x 1.2mm, 2 x 1.4mm, 2 x 1.6mm.
If you have a Nextiny CE (Collectors Edition, only 131 out there... have #122 myself
) You get a 5-slotted airflow ring which allows for the use of EITHER a single-slot setup with the other four closed off representing your normal setup, or four open with the fifth closed off for massive airflow.
The Nextasis is a bit of a combo; with no AFC ring per se, it's central post operates similarly to that of the In'Ax but with a bit more thought included into it as you are able to use the same chimney to set up either single or tri-slot AFC. It has a total of five sets of dual-stacked airholes (2 x 0.8, 2 x 1.0, 2 x 1.2, 2 x 1.4 and 2 x 1.6mm) and effectively represents a 'combo' of the previous two atties, with room to spare, in a sense. I'll upload two pictures below that illustrate the point and pictorially depict the various size combinations/functionality.
*Viewing the atomizer from a bird's eye perspective, you select either single or three-way by aligning the corresponding dimples on the central mouthpiece/chimney piece with those on the flat surface of the top cap as illustrated below:
*Here is a chart describing the 10 possible combinations (combinations made by different alignment combinations):
So as you can see, the MOST possible restriction on a VWM atomizer can be achieved with the Nextgen using the half slot ring, yielding a total airhole area of just 0.9mm. The second most is the same atty using the half slot on the 1.1mm, the third most restrictive is the same atty on the 1.3mm, and the fourth most restrictive is the same atty on the 1.5mm.
After the half-slot Nextgen, the most restrictive is the smallest Nextasis single-slot setup, with 2x0.8mm or a total of 1.6mm (remember there is no half-slot ring for any other atomizer or the Nextiny/Nextasis would take it using the 0.8mm airhole setting).
The next most restrictive is a tie between the smallest single-slot Nextiny setup (2x 1.0mm or 2mm total) and the second-smallest Nextasis single slot setup (also a 2x1.0mm or 2mm total).
The
LEAST restrictive you can get on the NextGen is ([2x0.9mm] + [2x1.1mm] + [2x1.3mm] + [2x1.5mm]) = 9.6mm total.
The
LEAST restrictive you can get on the Nextiny is 1 x (2x1.6) = 3.2mm.
The
LEAST restrictive you can get on the Nextiny CE is ([2x1.0mm] + [2x1.2mm] + [2x1.4mm] + [2x1.6mm]) = 10.4mm.
The
LEAST restrictive you can get on the Nextasis is (as represented by the third box down in the right hand column) a total of 8.4mm ([2x1.2] + [2x1.4] + [2x1.6]).
There is something about the chamber size-to-airflow ratio between the Nextiny chamber and the single slot dual 1.6mm airholes that is the sweetspot for me (total of 3.2).
On the Nextasis, the sweetspot is the three-way setup for a total of 7.4 mm airflow (2nd box down, second column).
The sweetspot for the Nextgen for me is the dual AFC ring opening both the 2x1.5mm and the 2x1.1mm for a total of 5.2mm.
I just know this based on tons and tons and tons of exposure to all of these atties, every day consistently for months and months now. On occasion I will deviate from my sweet spot zones, like 4-play NextGen, single-slot 2x1.6mm Nextasis, three-way Nextasis for a total of 8.4mm, and (the only other option on this atty) the 4-way on the Nextiny CE for a whopping total of 10.4mm when I'm feeling adventurous (this setting is very much akin to a RDA-with-mesh experience).
While there do exist dual-slot Nextiny rings out there, they are mostly under-the-table/custom jobs and were never mass produced or even produced with the Nextiny CE. I haven't even been able to find one - I saw a Nextiny with single and dual slot AFC ring for sale once but to obtain it would have meant I'd need to have purchased the whole Nextiny, and I already have two. My feeling, though, is that that might be my favorite Nextiny AFC setup but again, I haven't tried it.
I also have machinist friends who have created their own dual-slot AFC rings for the NextGen whereby the two slots are oriented not 180 degrees from each other, but at a 90 degree angle, allowing for the combination of two adjacent stacked airhole options on that atomizer. Again, these are grassroots productions and not something one can necessarily purchase, although I'm sure I could request one made if I were so inclined.
Long-winded post. Apologies.
mate.. and am using it all the time every day!.. but looking forward to comparing it with the Nextgen, and seeing how they do..will certainly let you know!
