So I got them in. Yeah they feel like they have a little higher shoulder - little taller in general , the end comes to a point more-so than the proto - and they putted as if they had less glide and more dump. Basically its different enough to make me unhappy haha. The Proto feel in the hand was FAR better. The material feels more durable as well. This first run material reminds me a lot of a Gateway plastic or Trilogy Hard baseline ---- almost feels more like a McPro with Gateway plastic ---- which isn't a bad thing its just different than what I was expecting. Kinda bummed. I putted with them and they were fine. I'm sure I will adjust and as it wears it may feel and fly better.....but.....the proto felt and flew great immediately so. idk. Its still a nice putter and I'm gonna give it a go this spring but......really wish they just duplicated the Proto --- ah well. time will tell
