Argh, that's what I get for going away for a few months and then speaking off the cuff!
While they have apparently been the most reported for tears, I would argue that the data is skewed since the 4610/4612 is used on a disproportionately large number of vehicles. To draw a genuine conclusion we'd have to track successful filter runs and log a failure rate (% torn/not torn).
I recall the 4459/4460 being the poster child for tears & lousy construction (based on photos), but they're not reported as much since they're not nearly as widely used. As the used 4610/4612s tend to have more uniform pleat spacing than the 4459/4460s and 0241/0195s, I'd wager that their failure rate would be lower.
