Anodes and Ions do not turn over like other putters IMO which if you flip they often are not coming back and getting way off line (MikeC's aviar test video is perfect example where it flies fine most of the video but the one drive slight downhill and aviar turns over and disappears off the screen...) no anode or ion will ever flip that much. The HSS of MVP putters is wayyyy up there compared to other molds in similar stability. There are more OS putters with the same HSS but for fairly neutral putters you can mashhhhhhhhhh them.
