I forged with the 65 and I am happy. My 110 is the old style withe the bolt on dies but it works great. The 65 hits faster and uses less air I have both hammers set up with different dies, combo on the 110 and crown on the 65 and I was back and forth all day. It hits different but I think I'm going to be very happy. I was going to get the 155 but then I realized I just wanted it because it was bigger. There is a lot of control with both hammers, I did everything from draw small tapers to cold texture flat plate yesterday.
