We have had some of our longer runs (280ft+) have occasional problems with all of the sync over power sources… sometimes its great for a couple weeks, months then stops, sometimes no go from the beginning, sometimes everything perfect.
The longer runs, at times, will definitely “stress” the dynamics of SOP in any environment.

I have 1 site that is Syncing off the Puck, but powered via a sync injector. I was having ethernet issues (interface bouncing/negotiation) until I disabled Sync on that port in the Sync Injector. It's been fine since.

Saved us many tower climbs already. As a rule, we keep the back to back APs on the same sync source (SOP or puck) and that seems to work fine, even with the other 2 back to back APs on the original SOP sync source.

We noticed sync compatibility issues when using packetflux sync injectors.” My advice is to deploy with the puck antenna and use it as your primary sync source, and keep the SyncInjector oprerational as a backup.
