This here is a prototype test run of the Soft Ridge. Insanely rare to find one scaled at 178.4g. Like new condition no ink, slight factory blemishes, practice putted couple times. This Soft Vibram is not labeled and feels a touch firmer than normal Softs but at above max weight that may be the reason, but it's definitely not a medium, and folds both ways in half.
This disc is truly a 1/1.
