Rainboe,
If you maintain F30(and Vref+5) SE and subsequently decide to go-around due profile loss,you have no option but to fly that GA with F15 up to at least 400,then get your 20 knots,take F1 and continue to 800 or 1000..which is why I believe the F15 selection and acceleration at engine failure recognition is a wiser move.Maintaining landing flap is poor judgement unless light.It seems to me the maintain landing flap position was advocated just so you wouldnt get the EGPWS FLAP warning which is a poor pretext.I would add that if the FO doesnt find the flap inhibit,then a GA would be better,unless ice runs through your veins.
