Yes, it is dead weight, but the seamless/same diameter looks better then it tapering in. The ELA is already a beast, so at least it'll have and equally beasty feeder.

I see what you mean. Area = πr². It's been a while since I had to play with geometry.
So if a 1.32mm dia hole has an area of 1.37mm², four identical holes have an area of 5.47mm².
Using four 1/16" holes would give an area of 7.92mm².
A 3mm dia hole has an area of 7.07mm². Two 3mm holes ≈ 14.14mm², almost twice as much area as even the proposed increase. A graph helps to visualize:
So even if the hole size were increased, it still might not be enough to satisfy the dragon chasers entirely, but it might help.

The helix air flow with the multiple air holes might do the trick just fine..
Since to my knowledge this has never been done before, we will have to wait and see..
It's one of the things I def plan on testing out!

Total air hole size though isn't the only thing that needs to be considered and is misleading. This has a smaller chamber volume compared to other rba's/rda's of this size I've seen (as I've mentioned pics don't tell how small it is in there), so velocity through there is going to be increased vs dumping that air into the side of a big chamber which stalls the incoming air flow velocity past the coils and has poor distribution across the coil(s) which results in less vapor and the need to dump more air into it to compensate.
The Strata's holes don't just dump into the side, they distribute equally all around and into a small chamber, so airflow across the coils and the resulting vapor is increased as well as the cfm moving through there.

That reduced chamber should also pump up the amount flavor coming out of it as well. As fun as it can be to see a humungous plume, I'm not much of a cloud chaser...it' all about flavor for me.
It'll still be a fog machine too if you want, wrap some multiple coils and open her up!
The problem I see with side air feeds is the crappy distribution. Most of your air charge is coming through the air hole, taking a right turn and immediately heading up into your mouth, not properly distributing over the coil(s), which increases the amount of air needed to produce a given amount of vapor. The Precise Strata solves this.

I will test it out for all the cloud chasers out there! 
It's not my cup of tea but in the interest of science, I shall do so..

Heres an example of the relatively small size of the Precise Strata's Chamber. You'd think the smallest one on the right would have the smallest chamber but:
Chamber Volume in CC (base protrusion into the rba's taken into account) :
Left : 3cc
Middle (Strata): 1cc
Right : 1cc
View of the chambers:
Next up you see the air holes, the Precise Strata flows up to four times as much air as these examples and is adjustable all the way down to no airflow. Airflow volume should not be an issue on the Strata:

It is a very interesting design David and am looking forward to hearing the first reports on here.
The air entering more evenly at low level via chamber prewarmed, multiple inlets instead of the normal fine jet spray is a lovely feature.

Sure, heres the skinny on estimated release times, release order and preorder information: Super T ~ Strata RDA
awesome.. ELA version pre-ordered and paid for.. thanks david for the opportunity..
question.. after the "strata testers" have tested and get back to you on their findings and opinions, if they all come to a consensus that something needs to be changed or tweaked will you take that in consideration before the final production starts?
