Efke 25 is not orthochromatic, but rather panchromatic (with reduced red sensitivity)! A quick look at the spectral response curve confirms this. I would suggest loading in complete darkness, and processing normally; that should solve your contrast and fogging woes (fog reduces contrast).
Efke print film is not efke 25. Two different things. Freestyle sells both. I can't help beyond that, just wanted to clarify.
