Testing the #2019proto so far has been fantastic!! Both models right out of the box feel softer in my hands. The covers feel great and the dimple patterns are amazing. On the green the balls feel amazing off the putter face. Much softer than their predecessors. It almost felt like the outer core transferred the energy to the inner core and back out again. But much more fluid. Putting included comparisons against the 2017 #prov1 #prov1x #avx using a #scottycameron Newport 2.0
