Words directly from MVP – “The Ion’s beaded rim design makes it a straight to overstable flier. Power putters can use the Ion with confidence. It is capable of holding long powerful lines with a late subtle fade. This makes it a very versatile putter that can be used in all conditions”
If that isn’t enough proof that you should buy it then I don’t know what to say, approved on 9/14/09 cannot exceed 174.3
