What Mizuno Says:
The new M.CRAFT OMOI introduces heavyweight stability to Mizunos forged putter line-up renowned for its precise looks and feel. The OMOI achieved its new stability by taking a view of the entire club balancing out the increased headweight with a lighter weight grip and shaft to shift the clubs CG and help control face rotation through the putting stroke.
