UnSharp Mask

I just noticed the unsharp mask in Fusion7 has been changed. It no long has a slider to allow to adjust how the tool affects the dark values of the image. What is the thinking behind this change? The threshold slider does not seem to have the same results.
This is causing a minor headache when bringing in shots previously created in fusion 6, and I was wondering if there was a known adjustment that can help...
thanks
