I'm using the B&S Cyanotype kit. Where can I get the Mike Ware kit?
B&S may have it is well as Photographers Formulary, but it is very easy to make yourself.

From what you describe you need a softer tonal range and just switching to the Ware formula will most likely give just as contrasty or more contrasty results. Why not try the citirc acid first.
