Whether you're trying to break 100 for the first time or par for the first time, all golfers can achieve lower scores by improving their strategy with wedges
Improve your play with "scoring clubs".
The first step in lowering scores is improving your play from 120 yards and in. Using deWiz to help master various swing lengths with your wedges goes a long way in achieving this!
But, it also comes down to strategy with these scoring clubs. Whatever scoring mark you may be trying to break for the first time, the key is always to try and eliminate double-bogeys (or worse) rather than making birdies.
This means identifying where the trouble is, understanding where you "can't miss" and choosing your target, club and Length of Backswing that will minimize the chance of reaching that trouble.
