A hardface weld will last if you can get it to stay without flaking off. Keep in mind they need to stay balanced in pairs installed opposite sides of cylinder from each other. The last set I bought from Agco were all the same(I believe 19.8 was written on the back of each one). It was about 6 years ago, memory is hurting me now. We did have a set of Ausherman's in there and loved them but let them get away from me, they seemed heavier and had more swinging weight and would hardly ever slug.. If you are mainly beans and corn keep with wide spacing bars whatever the brand...
