In cooking a loin tip roast for the time, I learned that it doesn't need to cook as long as I had previously thought. A nice sear for 15 minutes in a 450ºF oven and a slower roast for about 90 minutes seemed to do the trick. I presume that you could even sear it for the initial 15 minutes in the oven and then cover your roast with foil to lock in a lot of the moisture, maybe even add some stock to the bottom of the pan to help steam the meat.
