Works well with HB or darker leads just fine. If you're that kind of person Leuchtturm even makes branded pencils to go with their books. I did try a Rhodia pad for my mathematics once when my order with the store was delayed and it wasn't as pleasing. It worked fine but the lead does smear a little bit too easily for the reasons you mentioned.
