...why not use FP4 to start with?

Beyond several shortcomings of FP4 Plus that others have described, primarily because FP4 was discontinued in 1990.

Yup...that original FP-4 was great souped in either ABC or PMK Pyro. I miss it!

[Drew Wiley]

Very little visual difference with the '"plus" version in any developer, including my standard choice, PMK. The biggest improvement was a less fragile emulsion now no longer needing paper inter-leafing sheets in the box.
