Olympus 45mm v. Olympus 75mm

Hey there kind dpreview.com forum folk!

I'm in a bit of a situation. granted, nice situation, but a situation nonetheless.

I'm torn between getting the olympus 45mm f/1.8 and the olympus 75mm f/1.8. Yes, the 75mm has its seductive claws in me. That front element and the all-metal construction are sexy as hell. But My main concern is the focal length: specifically, does an effective focal length of 150mm excessively flatten someone's face as compared to a 90mm effective focal length?

I'm especially interested in feedback from people who have experience with both focal lengths, or preferrably, both oly lenses.

Thanks, and keep it real.
