For crazy control of your deessing I use the E²Deesser by
Eiosis, Your Talent Deserves This. You can download a demo to evaluate. They will most likely try to entice you with a discount after the demo expires. My demo expired and a year later I asked for the discount and got it. I used to use the waves ren desser and the uad precission desser but found the E²Deesser to be better (for me).
