Unless I completely misunderstand (quite possible) I would think enlarging the restrictor hole without the use of an IPR would make solenoid starvation even more prevelant.
Not even sure what a cut down filter would do or if those filters are replaceable.
Yes the mod is reversable. The cut filter will make no difference as it only removes about 1/4 inch of a nearly 2.5 inch filter. Not to mention the gun will work exactly the same without the filter completely, although in that case you would need to use clean air. So as far as the IPR modded filter goes it will function the exact same as a stock filter whether or not the IPR kit is in the gun or not.
If you go with the optional step of drilling the body out and then for some reason decide not to use the IPR kit you could increase the chance of solenoid starvation. If you don't want to drill your body out then that is fine as you will still get improvements from the IPR kit alone.
As far as reliability goes, the piston is the only moving part on the IPR kit and it is made out of delrin so there is no need for routine maintanence or lubing at all. The valve seat uses common shocker orings so it is completely rebuildable and the magnets will hold their tension for longer than the gun will last. Basically the IPR kit will be a set it and forget it system.
