Hmm, We were always taught with SE approaches to only put in Flaps 10 gear down a dot above glide slope intercept (less drag) until you have the runway in sight then you go flaps 20 or 30 and land. You can easily land a light twin with flaps 10 and have plenty of time to roll out unless its 2000' field.
Now, if you go missed all you have to do is gear up wait for speed to increase then clean up the flaps after speed is at "blue line".
