If your uplines are straight then your wings should be fairly close. That is a good place to start anyway. Most people tend to run the same amount of throw for down elevator as they do up, which means the down is going to feel sluggish as it takes a certain amount just to fly level, so I tend to run a little more throw, plus I even run expo to make it more sensitive around neutral so that I'm not having to push harder than I want to.
