Viewing the full size crop at 72 DPI on my Ancient Hitachi SuperScan
Elite 751 is the reason I don't think I need more more megapixels or a
bigger sensor at this time, though I do need a good tripod.

Zos, eyebrows are my litmus test for system sharpness. Get a well-lit
headshot of somebody and examine their eyebrows. You should clearly
see the individual hairs. Any time I handhold to get such a shot the
eyebrows are invariably a gaussian smear. You cannot do clean
retouching of such images.
I can show you a 100% crop of my model's eyebrows from the last beauty
shots I took using a tripod with my K20D and DA* 50-135. Clear, sharp,
detailed. I defy you to get that clarity handheld, no matter the
shutter speed.
Let's make sure we're testing the same thing. What percent of frame
should the person's head be? Any other requirements?
You want this to be scientific? This is The Internet. :-)
Well, the shot I have In Support of Tripod Use is this recent one:

Obviously head fills the frame, landscape. Camera was about 8-9 feet
away, 135mm at F8.0, ISO 200.
Probably not the best tripod for the task, the ball head is a bit
light for the DA* 50-135 + K20D: Manfrotto 190XproB, 486RC2 head.
Here's a 100% crop of her right eyebrow and eyelashes:

It's an 8-bit TIFF, exported from the original RAW shot in Lightroom
4. Lr's default zeroed settings except WB: flash and the default RAW
sharpening of 25.
