36-25 is not a hill gear, at least where I ride in MA. Mt biker background. Whatever pitch the hill, for me it is easier to spin than mash. I like a 1:1 ratio at least. So start with a 34 up front, go to a 30 out back,( or more) maybe might need a new rear der. as well. Touchy subject here, pure roadies will scoff. Only you can determine what works for you. I did a lot 22-34 spinning on my loaded touring bike last week. NH has some hills.
