What is this "one province-one unit" system? Is it on defense? And the other tactics you mentioned? For some reasons halbediers did not fare too well for me so far - probably I did something wrong...

As for the Mongols, I tend to use a spears-arbalesters-light cavalry strategy. Although you must have the best spears otherwise they will not withstand the tremendous heavy cavalry charge and once the line is broken, all your units rout at once... If you're able to use polearms (hallebardiers) then do it.
