Here’s my 2 cents after doing 6 pf/ppf builds. Always order the PF dwo.
it could be the batch of PPF overlays that I got, but man, I couldn’t get the dates centered no matter if I used it with the PF dial or PPF dial. It was very frustrating and took me a long time to compensate one side of the wheel only to have the opposite side off centered... which was better than having all the dates off Center.
after my ocd kicked in for half of the month, I ripped them apart again to swap in PF datewheels.
With all due respect to the folks here for putting in the time and effort to make these overlays, it’s my personal opinion that the PF dwo works well with PF and PPF dials.
