16x20 = small paper

Did my first 16x20 prints from the 8x10 neg Sex Worker Series and damn if 16x20 looks to small! I can only go up one more size to 20x24 paper, I have a feeling after awhile that will seem to small also!! Wish they made larger size Fiber papers! No wonder Richard Avedon went super large with his "In the American West" photographs, with these large sharp negs you can keep enlarging and enlarging and still get amazing detail plus tonality.
