What did you think about the prototype putter this year?

I found that I really liked the Discraft Ace Race disc this year. I normally throw a soft X Challenger and found that the Pro D prototype putter was very similiar in flight compared to my beat in soft Challenger. It was super straight flying for me. I would say they were a nice change of pace from midrange discs, perfect for those 200' or less control shots. Thank you discraft!
