Likewise I abandoned the HB Sport a while ago in favor of my trusty old Personna M5 Magnum. For me, though, the HB proved to be the key to the blood bank. No matter how careful I was, no matter taking my time, blood loss was inevitable and considerable. Funny thing was that when I started shaving with the HB everything was great. Then one day I bought a new batch of carts and the flow began. Same thing with the next few purchases of carts so I just dropped it.
