If you ride past storefront windows, look. There's a danger you will "pose" for a camera but those windows don't lie. (I raced many years ago and always looked to see how horizontal my back was. I am aerodynamically not a whole lot better than a leaf. That flat back was critical!) For you, it isn't how horizontal your back is but how straight it is. Now, I find bikes with longer reaches tend to stretch out my back and actually bring me relief. I think of it as being like a cat stretch. (Those stretches where they become impossibly long.)
