Following my last post of different wedges in your bag, I now would like to discuss how you can put these wedges into play. The drawing above includes my 4 wedges in my bag: Pitching Wedge (PW), Gap Wedge (GW), Sand Wedge (SW), and Lob Wedge (LW) and the specific lofts of the clubs from the manufacturer. As you notice each wedge is around 4 degrees difference therefore my wedges will be around 10-15 yards difference between the clubs. I then proceeded to write at the top of each circle approximately the average distance each club goes in my bag. I like to round to nearest tenth for my purposes but you can figure out what you specifically like to do on your own.
Now for some math! In order to figure out the rest you take the full swing yardage (at the top of each circle and start dividing. Again, I like to pitch using 1/4, 1/2, and 3/4. These best suit my swing. But you can also determine 1/3, 2/3, etc.
For instance my Pitching Wedge:
Full Swing: 100yds
3/4: What is 3/4 of 100 = 75
1/2: What is 1/2 of 100 = 50
1/4: What is 1/4 of 100 = 25
I do this for all my wedges. Now I have a chart of all the distances my wedges can go. After this chart is complete, I can go out on the range, using my range finder and find different distances. Once I choose my distances I can look at my chart and start hitting various pitch shots to each distance.
