Thanks for the reply Mike.
I figured this was the only time I'd ever want to get THIS close to the toilet. Once they're hooked up and in-use, toilets aren't exactly places where you want to poke around and investigate. I'm an engineer, so of course, I have to totally over-analyze things.
I'm shocked at how deep the bowl is. No doubt, this is a large reason why the toilet is skirted. The bowl is nearly 15" deep, with an estimated water spot that's 8-9" deep. For reference, my POS American Standard toilets only have a water spot that's 4.5" deep if you're looking at the total depth of the water, including the bottom of the trapway, only 1" deep in the bowl (on both the elongated POS AS and the round POS AS.) Ironically, the surface area of the water spot in the Aquia is nearly identical to the POS AS Compact Elongated I have... so the extra depth of the Aquia should be a real improvement and reduce the odor issues I've had with the AS. Likewise, the POS AS Round's tiny trapway and shallow water spot meant that most of the solid waste was exposed to the air. So, in my case, the dual-flush toilet looks like it's going to have less soiling and smell associated with its use.
Basically, I can "see" how this is going to work...and I believe the varying rim hole sizes are engineered to maximize the fluid dynamics, very clever. I'm very impressed with it. For once, something which I look at and haven't had something stand out as being in need of improvement. I also can see where the Toto seats come into play. If you're lined up with the "funnel", then all is well. If not, then it'll be a less than optimal experience. I did order the Toto Softclose seats... couldn't justify the extra $$ for the Softclose Oval seats and I don't think they quite look as good... hoping the seat on them isn't that different from the regular Softclose.
Other things I've noticed and liked:
1) How small it is! This is an "elongated" toilet, but it's smaller in size than the POS AS Compact Elongated and the POS AS Round, drastically so. The Round is 28" long, the "Compact" Elongated is 30" long, while the Aquia is only 27". Even the width/size of the tank is tiny! If you thought you didn't have room for an elongated toilet, take a look at these, you might be surprised.
2) It's far better looking than I thought it'd be... I know, I know... it's a toilet.. but it actually looks good. Just changing out the toilets is going to make a difference in my bathrooms.
3) Concealed water supply. This toilet is about as close as it gets to a 1-piece toilet in terms of looks & such...but at the same time, I've never seen a toilet where the water supply line can be concealed.
If they perform even half as good as they look, I'll be happy...but have a feeling they'll perform far better. At any rate, just looking at the engineering on them, they'll easily outperform the POS AS toilets I've come to hate. At the same time, the AS toilets have given me a possible 2nd career path if I ever choose it, as I've become well-versed in the usage of a toilet auger with those.
Also, does anyone have any good dual-flush signs or possibly a .PDF version of the sticker on top of the tank? I'd like to remove the stickers, BUT want some way to notify my guests of the "proper" use in a tasteful manner. The dual-flush makes such sense to me. This past weekend, I used an old 6-gallon toilet from the 1940's... seemed like such a waste to use 6 gallons to flush down a minimal amount of urine.
