can't hit long irons. Their faces are just too steep.
There's a point in the set where the clubs
become the enemy. It's where you
lose the ability
to hit quality shots. For most of us
it's between the #6 and #7 irons.
When you try to hit clubs you can't
hit you waste shots. The shots you miss, plus however many strokes it takes to
recover from the shots you miss.
If you're thinking you can't hit woods
either... It's more likely that you just can't hit the steep faced conventional
#1, 3 and 5 Woods.
High Lofted Woods are much easier to hit than Long or Middle Irons.
