We did a MOI list of some popular putters years ago, but we have not done it in a while. Ralph did a study on putting and what matters and what doesn’t in putter design back in the 2006-2009 time range I think, and had a list showing the MOI (Moment Of Inertia) of putters. Because, in our opinion, MOI is 90% of what matters in putter performance (from the heads standpoint) that and head weight is really all the list had on it. We stopped it because as tough as it is to try and keep up with the Iron MPF, the number of putter models we would need to acquire would be a lot more. So, we do not have a current list of late model putters with MPF/MOI.
