I've never had a tough roast on my 50 years of cooking! Regardless of the cut!
After I lightly oil my roasting pan I place my roast in it and turn to coat lightly with the oil. Season, cover and 350*. I watch my roasts - if liquid is needed I add some - if too much is accumulating, I remove the cover and take out some of the juices and save in the fridge for making gravy. I remove the cover for the last 30 minutes or so for a nice browning - all depending on the roast and the size.
You can sear to seal in the juices if you want and then roast or place in the crockpot.
Crockpot cooking is nice - it can also make your meat stringy - depending on the cut.
Just be patient and it will turn out for you.
