Does anybody have experience with the DXV collections by American Standard? We're looking to replace three builder grade toilets in our new construction home that are clogged VERY often by our seven year old! We've narrowed it down to the Toto Drake II, Toto Ultramax II, and the DXV Lyndon (one-piece). The Lyndon wins on looks alone, but hard to find any reviews of actual performance. The specs seem to be in line with the Totos and it has a great MaP flush score of >1000.
