There's nothing at all wrong with running a full flow filter to catch the big chunks, but keep the bypass filter on it as well to strain out the smaller contaminants. If you follow the example of the commercial engine manufacturers such as Cummins or Detroit, they have both types of filters installed. The filter media of a full flow type must be fairly open-weave, to allow enough volume to get through to supply all the engine's demand for lubrication. The only way to do that is to do a mediocre job of filtering the oil.
If a very close-weave element like a Frantz toilet paper filter is installed in tandem with the full flow, it will clean up the oil a lot more effectively, while the full flow protects the bearings from grains of sand, horseshoes, and small boulders!
