Experimenting with tire pressure sounds interesting, and would be a lot 
easier than comparing different sizes and brands of tires.

But I'm skeptical of anyone's ability to "feel" the probably minor 
differences that would result from five or ten psi upward or downward.

I think the most practical way of detecting a difference would be to use 
a road with a consistent, slight downward slope. Coast down it 
repeatedly with different air pressure and note speeds. Try for days 
with no wind and consistent temperatures if possible.

And keep in mind that if the difference is difficult to detect that way, 
it probably doesn't matter for most riding.
