20 works just fine
Just to add one thought to the good advise you have already been given... I have hunted Pheasants in SD for the last 18 years and am booked again for this years hunt and you can bet my 20 will be with me. If recoil is a problem consider an auto loader instead of a pump, it will take some of the punch out. I have used both 2-2/3 and 3 inch shells in #5 and #6. Cant really say I have a preference. Good hunting!
