I'm deciding between the Ultramax (with 1.6 g flush) and the Ultramax II (with 1.28 g) - formerly called the Gwyneth I think.
I like the idea of the double cyclone bowl flush on the Ultramax II, but am wondering whether the lower volume will compromise the performance.
It does look like the II is similar to the Soiree/guinvere in terms of features, other than the full skirt.
So what do you think ? Will I regret going with the lower flow ? (saving more water is not the issue, as it will replace a 30 year old toilet).
