I owned the original Well Tempered years ago, and sold and set up quite a few over the years. The latest golfball version is a joke. It is simply an exercise of how to reduce the manufacturing costs and claim it's better. I would rather have the original. By the way they released the Well Tempered player - a cheaper version of the original, and that was junk as well. The Signature is the best by miles, followed in my view by the original.
