Ok, i finally made the switch today, and let me tell you, it is great! The X behaves like a different car, it even has a more luxurious feel to it. It is much quieter all around. Surprisingly, I don't think the road feel has changed, which is great given that the Michelins are much softer. In terms of taking turns aggressively, I think they feel very natural and predictable. I will share more, once i get some more time to drive it around.
