I,m not a guru or anything,but I have been using hitters pattern for quite sometime and I can only tell what works for me.
Firstly, set-up at impact address ensure that you have (right hander)FLW and maintain BRW all the way through swing,take that condition back "ON PLANE"take it back to bit more than shoulder height.
secondly,ensure you feel the lag on first joint on index finger,maintain that pressure point all the way through swing
dont try to hit too fast,get the feeling that you are driving your forearm into the ground.
I,m some guy,s here will give you a better picture and explanation than me,but in answer to your question,you dont take club straight back perse ,you take the club back on the plane.
Hope I have helped in some way
