A little roughness in the trapway helps. To test this, throw a baby wipe on a textured wall one on the mirror.
The baby wipe on the textured wall will fall off first.
Either the CST744SL, CST744EL or the Drake II CST454CEFG will work fine.
This year I have an ileostomy bag, so for that, I like the Drake II. Of these models, only the Drake II has Sanagloss.
While you are looking at toilets, the Vespin II is good too. Skirted bowl, and Sanagloss.
