IMO, Unicot, dulicot, etc are hard enough as it is to use to get good results all the time never mind on a hard TI razor. I can set bevels with my coticule because it is fast but I wouldn't want to hone all the way through on one, it'd be a pain in the a** and cost me a lot of time. I go to my BBW after coticule and slurry for the bevel to add sharpness, this way I don't need to calculate how much water I am dripping off my finger is good enough or not for my honing. I then just go back to water on yellow coticule and then finish on an Escher with slurry.
I know you want to keep it simple but it really is good to have a norton 4/8k laying around in the background incase you need to hone differently.
