Definition: The up or down movement of the club head at the time of maximum compression. Attack angle is measured relative to the horizon.
The general rule is that shots hit off the ground should have a negative attack angle, and shots hit with your driver should have a positive attack angle in order to maximize distance.
Club head speed also plays an important factor in attack angle. If a player with a slow club head speed hits down too much on the ball (negative attack angle) they will typically struggle with carry distance. On the other hand, if a player has a fast club head speed and does not hit down on the ball, they will typically launch the ball too high.
The correct attack angle is vital in order to optimize your trajectory and distance.

Attack angle can also correlate with a player’s ability. Typically, you will see high handicap players with a low angle of attack (irons). In general, low handicap players tend to hit down on the ball more than high handicap players (irons), especially touring professionals.
Definition: The vertical angle of the club face at the center point of contact between the club and ball at the time of maximum compression. Dynamic loft is the amount of loft on the club face at impact and is measured relative to the horizon. (Think delivered loft.)
Attack angle, shaft profile, release point, clubface orientation and location of face impact can all affect dynamic loft.
Attack angle, shaft profile, release poinCreating the proper dynamic loft is important to create the optimal trajectory and maximizing carry. Too much dynamic loft will send the ball too high and reduce distance. Two little dynamic loft will send the ball too low, minimizing carry distance and causing excessive rollout.
In general, I typically see amateur players with too much dynamic loft on both their irons and woods, particularly with the driver. Better players almost always have a lower dynamic loft when compared to amateurs, in both Irons and woods.
Dynamic loft is also an indicator of the players current ability. Good players will almost always have forward shaft lean at impact causing a lower dynamic loft, where amateurs do the opposite and increase the loft or flip at impact.
