I would suggest to get at least one SW-16 and one PD-16 with the P3-Roc to control your flippers. Modern coils won't work with EOS only at 48V. Getting another control system (such as OPP) just for the whitewood does not make much sense in my opinion.

This is mostly a matter of taste. Flippers from different eras play differently. Choose what you like then go with that. If you like WPC style get those. Those are readily available on the market. You can also get Stern flippers. Early Spike flippers were dual-wound but they are back to single-wound with later Spikes. In general, single-wound works fine but it might be a bit louder which makes a difference if you test with glass off.
