A common pattern for lower handicap players is an aggressive tug of the arms in transition. This can lead to pulls and even severe hooks. If you pay close attention, you will notice that in this pattern, the hands are working down (and not up) through the majority of the release. A great way to combat this though, is by training some low-to-high releases where the hands are working up (and not down) through impact; adding the alignment stick to start will also tie together the larger muscles in transition and the release, which should further help to eliminate the left miss.
