I have a Canton filter on the scavenge side before the front oil coolers, a System 1 filter between the cooers and the front oil tank, and another System 1 filter replacing the engine oil cooler. I've never gotten debris from engine blow ups back into the engine - the final filter has always been clean of debris.

I did find that the Canton filter would explode when the engine blew up and the debris load was excessive, similar to one of the photos. I replumbed it so the oil came in the side port, and out through the middle. This seems to work better, though a large burst of debris will crimp the filter across from the inlet hole. It still has kept most of the stuff out of the coolers, and the pre-tank filter seldom has anything in it either.

On another note, I like my engine filters vertical and facing down. Not only does this mean I don't make a mess when I spin it off, but I can pre-fill it with almost a quart of new oil when it is time to put oil back in. Though a System 1 or a Canton just needs to be vertical because you can take the top off and suck the oil out if you haven't blown it out with air already (no blowing the engine filter oil back into the engine, though).
