I personally like my f150's. I know the weight of my runner helps when it comes to flexing but they ride like a caddy on the road, I was amazed. Chevies are just too long and stiff, they have to be at the point of being worn out before they even flex good without having a double shackle in my opinion. Some people swear by them though.
