No, QR is not irrelevant. Some grip better than others. We don't know what QR you have so some info and a photo would help but if you can beg/borrow a good Shimano or Campy QR to test it out you can at least determine if yours is the problem before buying anything. If it's not the issue you can at least move on to finding another cause of the slipping.
