I know exactly where you are coming from with this! When I went in for my first road bike they kept asking me how it felt. I kept reminding them that I hadn't been on a road bike in 20 years and didn't know what it was supposed to feel like. So, they ended up having to look at my position to decided when the fit was generally right. It ended up good.

Keep in mind that the fit can be tweaked and optimized later with a new stem, etc.
