I'm probably getting pretty anal here, but where else could one even think of asking such a question?
One would think the TOTO Carrollton and TOTO Drake are close cousins since they both use G-MAX technology. A large water spot (10-1/4" x 8-5/8") is claimed for the Drake in one of Terry Love's reviews, but I have never considered our Carrollton's water spot a large one. It usually flushes on one try IF you're willing to stand there and hold its hand for 3 seconds, but the skid mark syndrome is definitely more common than it was on the high-gallonage throne which the TOTO replaced. The pressurized Glenwall in the basement has much better bowl wash, but it should be rated PG-13 for violence.
Anyway, since most of the TOTO praise on this forum seems to be for the Drake model, I was just wondering whether Carrollton is supposed to perform as well as Drake or whether it is a comparative underachiever.
