I have the MS/2 from Discount tire, and so far it's a really smooth ride compared to my previous Bridgestone Duravis tires. The only thing I have noticed is that they feel like they squirm, or drift a little in the wind when not towing. Straight as an arrow when towing. I don't know if it's the soft rubber compound or what. It's not dangerous feeling, just a little odd.
I switched to the MS/2 because a friend of mine had Michelins dated from 2006 and still had decent tread after 70K miles. He just replaced them in 2016 because of age cracks. My Bridgestone Duravis tires only lasted 4 years and 35K miles and had significant wear on them.
