Good time to compare full flow with bypass systems:
Full flow:
Pump>filter>(filter bypass>sump)bearings>sump>repeat.
Bypass:
Pump>(filter>sump)bearings>sump>repeat.

An explanation of the routing:
Full flow filters have a pressure relief bypass to prevent the filter from bursting.
Bypass filters have no such pressure relief, nor do they need one as their output is not essential to the needs of the engine. This means that the full flow will always have a percentage of unfiltered oil pumped through the bearings, so it is essentially similar to the bypass system in that respect.
Why choose one over the other? Because the bypass filter removes all particles down to just half the size the full flow filters remove. Your choice.
