KOhler Memoirs is a class 5 but is their a class 6 that matches the MEMOIRS Pedestal?

Im buying a pedestal Memoirs Kohler, but am afraid to get the class 5 cimaaron... I need everything to match.. Do they make a class 6 that goes with the pedestal?? Also, I am thinking of going with a Clayton TOTO , that could match... Any other toto's that look like the Clayton that have a better cleaning of bowl than Clayton?? Thanks

You can order the CST424EFG Promenade with CEFIONTECT.
