When I tested it I found that "In-Swinging" was more dangerous than "Out-Swinging" but the different was not so drastically huge to pay it crucial attention. Also, to have "In-Swinging"/ "Out-Swinging" for both sides you need use different corner takers and usually some of them have higher "Corners" attributes than other so at the end I decided that it's not worth bothering and I just set the players that have the highest "Corner" attribute to take the corners, of course, if you use my corner setup you should choose from your players that play only at ML/MR positions.
