It just energy management. My cub would never make the runway full flaps 42IAS on down wind if the engine quits and at that speed and flap configuration I would feel I gave up all my energy. But the Pilot has to be confident is his approach that's important so what ever he is comfortable with is probably best for him.
I would suggest New cub pilots to find a good instructor and practice, fly every landing like an emergency when you have one it will just be another landing. Pick a spot!
Randy for what it worth I have always used a pretty steep approach and found Cubs don't want to 3 point especially solo if its to shallow of an approach, steep approach don't level off just bleed it all the way to touch down maybe something to try next time you 3 point and those were some great points about being outside the plane.
