I agree. But after 3-4 more weeks, don't hesitate to backsweeten. I like using apple juice concentrate. It provides more apple flavor, as well as sweetness.
Also, remember that if you backsweeten, you need to kill off the yeast, or it won't be sweet for long... those little yeasties will go to town on that sugar.
