Avoid Toto 1.28 gallon if performance is most important?

Hi,

I'm surprised I didn't see any mention of the 1.28 gallon Toto's but I assume if performance is biggest concern these should be avoided?

I couldn't find any details about this on the Toto site but when you select watersense (1.28 G) the Gmax option disappears so watersense is obviously not Gmax.

This has been gone over before, but here it is again.
I sell about 50/50 1.60 vs 1.28
Many of my customers have both now, and the word is that they really can't tell a difference.
I have a 1.60 downstairs and two 1.28's upstairs.
The 1.28 has a weighted flapper, so if you really want more water, you can hold the handle to force more water out.

The 1.28 Drake ADA is rated 900 grams
The 1.28 Drake II ADA is rated 800 grams
Anything 500 grams is super.

Thanks Terry,

I searched for 1.28 on the forum and no hits.
