I am looking at some York bars that are 30 and 32mm respectively in diameter. A lot of power bars I've seen are 28.5 mm. I am concerned that a thicker bar will be bad for deadlifting. Is this a worthwhile concern or can a 32mm bar still flex some?

edit: the bar product numbers are 32120 and 32121.
