OF course that decision isn't "cut & dry" easy!

First did you flush the system? How much oil came out of the old compressor?
How much oil was in the new compressor? Did you replace the drier or other a/c system lines? Was the complete system flushed with the correct a/c flush?
Was there any other problem with the a/c "fluid" system? Was there any leaks?
How much oil was recovered during the R134a recovery?
