wierd noise after rotating tires?

Hey guys, about 2000 miles ago i rotated the tires and afterward i heard a binding type noise at about 20 miles per hour mostly when stopping. I thought maybe the rotors were a bit worped but anything below or after 20 mph the noise goes away. Also i can slightly feel it through the pedals. I didnt post earlier because i thought it might go away but its still here, hasnt gotten worse but its starting to concern me. Any ideas/feedback? Thanks.

front to rear is how i rotated them. They are directional. Yea I made sure they are going the same way. I checked all the lug nuts about 500 miles ago all were torqued to spec. I might have them balanced for the hell of it since costco will do it for free. I might try rotating them back to see if it goes away.
