Update: The link I had here was removed from youtube for "violating community guidelines."
The video briefly described then demonstrated the sterile tube method, and then the direct oral contact method (aka MBP or "metzitzah b'peh"), both of which accomplish the "b'peh" (with the mouth) traditions - though the first does not involve the mohel's mouth contacting the baby, and the second one does involve this kind of contact.
My main objection is to the use of the words "more traditional" for the second one. I would call it "more cultic" than "more traditional" because the only tradition it reflects is living in an ancient world.
Having said that, the track record is relatively good. But as I say each time, if ONE baby gets infected from the second method (and that seems to be the reality out there), then that method shouldn't be done, and mohels should opt for the first method, and parents should understand that it is more than adequate.
