Around town 30-40mph, you will need far less than a 70mph highway ride. It's just something you're going to have to experiment with an figure out where your comfort zone is. Don't wear too many layers, you don't need them. Turtleneck or mock turtleneck, the Gerbing and then the outer jacket. See how that goes. I never needed more than that riding in Michigan around the freezing mark.
You're going to feel the heat within a minute of turning it on and you're going to wonder how/why you rode in the cold without that stuff before...
