there are 2 tension spring. the one already in place is more than sufficient. does it feel realistic I can't tell you coz I am not an real pilot. regarding some real 787 pilots they do like it actually..I never ever felt sorry for buying it. the quality is top and non issue at all. if you are using just don't forget the fsuipc for msfs 2020 or p3d...for x-plane I have now clue. hope could help you out.
