I guess I'd be afraid of of accidently leaving a piece of debris on the wrong side of the filter media just waitling to get pumped through the motor. Of course in a Harley Twin Cam motor the oil pump is about the closest tolerance assembly in the whole engine, yet the oil goes though it BEFORE it gets filtered. All of the roller bearings in the motor will easily pass relatively large particles with little drama.
So far I've always used readily available and relatively cheap disposable filters in all my vehicles with no issues, I see no real good reason to change now.
