I have found that scanning at the higher resolution sometimes, but
not always, improves the scan slightly. For example I have one test
target that shows clearly better results, but scans of "real"
subjects are in most cases not obviously better. On the other hand
as you mention I have found these higher-resolution scans easier to
sharpen. My current thinking is that when I want to eke out every
bit of goodness my scanner can produce I scan at the higher
resolution then use Photoshop and bicubic interpolation to sample
down to the optical resolution of my scanner. You might try this and
see what you think.
