Well it all goes back to what you plan to use it for. If you is just an everyday driver worrying about that little bit of geometry will never be noticed in seat of the pants. That also goes for the high lift extreme ramp cams. If you are looking for driveability and dependability your cam will not be that extreme. As for ductile iron lifetime, I've seen irrgation pumps with old 413 industrial engines still running just fine with ductile iron rockers. Seems to me the time for roller rockers is when you are hunting ever ounce of power you can find. While I've not seen a trunion bearing go bad I have seen roller tips go bad and without a lot of mileage.
All in all, that what's great, to each his own, he was asking opinions, we all gave one.
