Here's one solution.
- duplicate the original layer
- run Filters>Other>High Pass with a radius of .3
- run levels with the input values set to 90 and 165
- set the mode of your new layer to Overlay
That's it - you now have a sharpening method that combines the advantages of both methods.
While we're here, there are some additional advantages to sharpening in a layer that I did not mention in the Sharpen 1 article.
- perform color modifications, etc, on your original image and retain the sharpening
- duplicate the sharpen layer to get even more sharpness
- alter the transparency or your sharpen layer to reduce the sharpness, or fine tune the sharpness of an added layer
- fine tune the radius and levels settings to get your own preferred result
