Offsets are all about Flow, if you pack it to full it'll slap land you at an AA meeting. So size matters. Figure average the size hog you will cook your gonna want the cook tube to be at min 2/3 larger in volume in Dia and Length. to keep the proper flow. If I was looking to cook Whole Hog and other stuff too I would go with a Meadow Creek PR 60.
