re: Question for any centers or QBs out there

No, the center just rotates the ball (to where it's hitting the qbs hand in grasping position) the same as he snaps it back, to where the laces hit the qbs fingers, or the spaces hit the qbs fingers, depending on how he likes to recieve the snap. It is the quarterbacks job to get his hand placement right. Unless the qb, specifies a certain way he likes the ball to be snapped, it is the centers job to snap the ball consistently and let the qb make any changes in his hand placement.
