Depends on what you mean by 'fault'.
Swinging too hard could be described as an 'issue' and a slice a 'result'.
Most poor shots are slices but most really bad shots, discounting misses, duffs/foozles and tops, are hooks.
Apparent and fundamental causes of bad shots are many and varied, but in the vast majority, incorrect (or poorly timed) tension plays a huge role.
excuse my ignorance , whats a foozle ?
