If you find yourself with a huge amount of pressure on your hands you may look into seatposts that have a setback built in. KOPS is nothing definitive, just a starting point. You may indeed need to move further back , or move a bit forward. Time will tell. Pay close attention to how your knee reacts and how much pressure you have to use to hold yourself up. If your hands hurt due to pressure consider a setback seat post as one thing you might try, but save up for a serious professional fitting. There is no substitute.
