Control of contrast can be obtained with various methods but it is always best IMO to expose and develop for the native range, if I may call it that, of a process.
In general there is no reason you should switch from D76 if you know and understand this developer. Dick Arentz used this developer al lot for pt/pd printing.
Many people use pyro staining developers for printing with pt/pd. I have found this class of developer to be especially good for very low contrast scenes where a very high N+ type of development is needed.
