As we've said before, draw resistance is pretty subjective. IMO so much so as to be almost useless as a benchmark.
Early on with Solo (that's the original version of Solo I) our good friends at Planet Vape (top notch supporter of these Forums that they are.....) developed, produced and sold a line of lower restriction stems. Still do I think. Those of us here then jumped right on board. They featured grooves down the side of the bowl (on the outside) and notches in the lip to give extra air passage. Much more than the current Solo II with it's larger vent holes. At on top of that a version with the bottom of the bowl drilled out between the four holes there. We found out that less draw resistance didn't give more potent hits, just bigger ones.
In the end, you got bigger, but thinner, clouds more easily. Slowing down some gave thicker hits......still does.
The issue it heat can only conduct into the load to make more vapor so fast. That is what limits actual vapor production. More air can only slow that down by 'stealing' heat that would otherwise make more vapor. Arizer is a solid outfit that knows it's business well I think, look at the products they produce in terms of utility (making vapor dependably) and longevity (they seem to soldier on and on with few if any breakdowns). Few makers come close in those areas. They no doubt tested the draw resistance?
Anyway, those who wish for less draw restriction (IMO mostly based on the blazing experience where more air means more fire bringing more heat to make more vapor) should check out PVHES (Planet Vape Hight Efficiency Stems)? I suspect you'll come to the same conclusions we did, Solo/Air/ArGo works best as designed. In the end all designs are a set of compromises after all.
Best wishes to all.
