I love your mirror idea, now can see what's going on and take the guess work out. Thanks

That's why I won't buy a piece with a neck coming from the top of a can. It's a design flaw, considering the fact that a bubbler style neck (on pieces with can's) allows you to actually see what you paid for.
I really have to disagree with you here unless you are being specific to stacking pieces with multiple filters. Vapor has many different flavors based on the perc, can size, and neckpiece/constrictions. pillars/vortexing in specific though I agree is somewhat pointless, although there is filtration that is different to be had in a pillar (haven't tested one myself) that may effect how quickly the vapor travels as opposed to the visual aspect of the vortex. To further that, I can distinctly tell the difference between dabbing or vaping out of a piece with little restriction/cansize (10mm micro tube / fc710/ shisha water pen attachment/ toro double micro to an extent), middle resistance/can (circ-turbine US blown 13inch, starbud cup, double barrel), and large (sov downgrid) and that they all have their individual flavors and different speed and pull clears.
The draw can feel different, and the intensity of the flavors can be different, but the effect of the vapor, and the flavor profile do not change from piece to piece, if you keep them clean.
If you take a huge hit from two pieces and blow the hits into a testing machine, one hit might be denser, but it won't contain different chemicals. it's not like a matrix perc filters out more CBN than others, and fritted disks filter more CBD. One can filter more of everything out, making the vapor less dense, but it can't selectively do anything. Glass is glass.
Ex. A diffusion pump may have stronger flavor than a gb-186, using the same herb, but that vapor is going to have the same flavor/effect profile on both pieces. One piece isn't going to taste like lemon and one like pine, if you use the same bud.
Personally if they were put in a bag I would think that a lot of flavor would be lost obviously, and to top that the individual bags will have different strengths of harshness but to a much minor extent due to the fact that they are bags and not individual pulls. I'm not sure what you mean by a single matrix though, as I would think a single matrix in a large can is enough diffusion for most vaping yes, but a stereo matrix obviously has a completely different method of added diffusion to it.
The different bags would all be affected the same way, so if vapor was put into them from different piees, the vapor that comes out of them should all be different too. Even if it is changed from when it went in, it would still be noticeably different if it was as big a deal as people make it out to be.

In regards to pillars, one thing they do, is allow you to have a piece with large inner volume, but very little space in which the vapor is being diffused/wet. The vapor gets diffused by the bottom perc, and then travels straight up the middle of the piece, before the bubbles can pop, which may be why they are supposed to retain a lot of flavor.

Basically, what I was saying in my original post, was that if you can't see the percolation and stuff happening in your piece, without some inconvenient mirror setup, I feel like it was a waste of money, since the vapor coming out isn't going to be THAT much different. There really is no need for having more than 2 pieces aside form aesthetics/compatibility with your devices, so you might as well get to enjoy the aesthetics.
