    I am debating where to get a Toto drake CST746 or American standard Champion 4. Champion 4 has a flush valve size 4" which is good, but I can't find the new Toto drake's flush valve size information on Toto's web page. I like toto's Dynamax Tornado Flushing system though. Is it only come with 2.5" flush valve? Is it powerful enough?

    Thanks for your help and opinion with this!
