I always used (even before B5 was totally banned) NBF but with special precautions regarding the pH that was checked for each batch and also all the Giemsa staining was done with pH controlled phosphate buffers. We never had a problem, nor a complaint from the pathologists.
  I advise you "to follow that path".
