American Standard toilets: "Champion 4" vs. "Champion"

We have three "Champion" toilets that we bought a few years ago. They
flush very well, but it was not long before the flush valves on two of
them (the two that get used most) started leaking: the rubber ring
became "flabby" and didn't seat well. I called AS, who sent a pack of
new rubber rings. These worked fine at first but started leaking after a
few months. I had kept the old rings, which seemed to have become
"firmer" again after drying out, and these worked fine for a few months.
I went through this cycle for a quite a while, but recently the "flush
tower" on one of them started sticking in the Up position, and the only
way to get it to drop back down was to remove the tank lid and give the
flush tower a firm push.

I filled out a customer support form on the AS Web site and they
promptly shipped three "Champion 4" flush valves, which I installed
yesterday. These work fine, of course, although I have read reports that
even with these some people have had problems.

The new mechanism does not seem nearly as sophisticated: the original
"flush tower" would drop and stop the water flow even if the handle was
held down, but the new one stays open if the handle is held down (or
sticks down).

Although AS sent new flush valves, they did not send new tank-to-bowl
seals. One of the originals did not survive the removal and replacement
very well and really needs to be replaced too.

Today (several days after I had bought a new seal) FedEx delivered three
sets of tank-to-bowl seals, bolts and bolt seals.
