The Ion is a new putter from a new company, MVP Discs. They are the first disc to be made out of two different plastics. The inner portion is made out of a champion or Z type plastic, and the outter rim is a softer rubber-like plastic.


I got two of these 2 weeks ago and I'm liking them so much I'm bumping out the Focus and putting it in my bag instead. The outer rim's rubber-like plastic really grabs the chains and makes putts stick that would have missed with any other putter. They glide extremely well..much better than my Focus, Wizards, and Magnets did in the past. This will be my disc to use for upshots or drives 200' and in. If you're looking for a new putter, I'd give this one a shot.
