30ft Don't overflare, (assuming you have it in the slot at 50 feet and on speed), about an extra 2degrees ANU getting rid of the thrust simultaneously, is all that is needed, then hold it steady. Gound effect will cushion you and tend to push the nose down. Just resist it, don't push or pull. IMHO.
No time on type but this worked for me on B727,DC9, MD80, 777. All the same but people like to complicate things.
