K or A. That would be really tough. Personally, I also like the A coatings' color reproduction, but like you the K lenses sure are well-built and probably optically slightly better than the A.
BUT If you may be getting out of the 80s, then consider auto-focus. You can probably sell the pair for most of enough to get the FA24/2. (And I could use the 'A' myself!) Collin
