Alright I was able to play three and a half rounds today with my Pure. It flies very straight and releases from my hand well. I can see how it might have more glide than most people would prefer for a putter but it worked very well for me. I think it can actually replace my Rhyno and my putter. I choked on a couple of shots with it but overall my putting was much better than usual. I also sunk a 60 ft shot and another that was over 80. I don't think it was 100 ft but it was damn far. I'm worried it won't do well in wind so I'm going to keep an Ion in my bag but other than that I would recommend the Pure to anyone who hasn't tried it.
I've never really felt in control of my putting before but something about how it releases and its flight pattern just feels really natural to me.
