2-10 will cover all your hunting needs. Or 1.7-10 as Doug posted. Not much more you can ask for. My main hunting rigs have 3-9, 3-12 and 2.5-10.
2-12 is even better when you are at the range, especially if and when you try to stretch her out for the longer shots.
Someone needs to come out with 1-12x42

All of them do something better than the 30-06, but none of them do everything as well.
