In this video, Michael Kunman gives you an example of what lofts you need when adding in specialty wedges.
When trying to gap wedge lofts, we look for between 4 and 6 degrees between each club. An example is below;
PW – 46 degrees
then go
50 degree
54 degree
58 or 60 degree
This will give you a consistent gap between each club when trying to approach greens.
