Well as I am in the dock, I shall answer that! What concerns me is going around with stuck medium setting flaps. You will certainly have to raise the gear! But what if you surge and lose an engine? Go around on one possibly, flaps stuck at medium, gear raising 'uncertain' or maybe slow? Bad situation.....and you are overflying 11000' of concrete, for which you would have used 4000' or so landing? Stuck flaps to me is a flying control problem, which means get it down as soon as possible- wait- that's too long! Sooner! Taking into account runway length, visual conditions, lack of defined go-around, I would rather plonk the thing down and apologise later. That is not to say to go-around is wrong- it depends on what you consider to be the 'righter' answer!
