It is important to note that the marketing of our putter variations is not just based on flexibility, but also on surface complexion and surface hardness! Even though we only state four discrete flexibilities in our marketing materials, SSS (Super-Stupid-Soft), SS (SuperSoft), Soft and Medium, we actually produce runs that have a range of up to ten different flexibilities!
Here's a rundown on the differences in putter flexibilities, on a scale of 1 to 10. A 1 is the softest surface and floppiest we make (think SSS), though realistically most SSS we make we shoot for are 2. A SuperSoft is a 4, a Soft is a 7 and a Medium is a 9 which wont really flex that much unless you really apply pressure (50% of the Mediums are probably closer to a 10 for players that just like firm discs).
There are many runs that fall in between these target numbers, like 1,3, 5, 6 and 8. Again - our marketing of Super-Stupid-Soft, SuperSoft, Soft and medium is not only flex, but surface complexion.
